Q. What is the difference between deep structure and surface structure?
As per Chomsky deep structure refers to concepts, thoughts, ideas & feelings whereas surface structure refers to the words / language we use to represent the deep structure. Deep structure is what you wish to express and surface structure how you express it in with the help of words and sentence.

Q. What is Surface example?
Surface means relating to the outer or superficial characteristics, or carrying something on land or sea. An example of surface is the texture of the top of a table. An example of surface is a person who appears honest but really isn’t. An example of surface is mail that is carried by truck instead of by air.

Q. What is a simple surface?
Summary. The statement that f is a simple surface means that f is a collection, each element of which is an ordered pair (P, z), whose first member P is a point and whose second member z is a number such that no two ordered pairs in f have the same first member.
Q. What is the formula of curved surface area?
The surface area of the cylinder is the area of a curved surface of a cylinder including circular top and base….Area =2 /pi r (r + h)
/pi | Pi, approximately 3.142 |
---|---|
h | height of the cylinder |
Q. What is CSA and TSA of cylinder?
Total surface area (TSA) of cylinder = Area of curved surface + Area of its two circular bases. Or, TSA of cylinder = CSA of cylinder + Area of its two circular bases. = 2πrh + 2πr2 sq. units. So, TSA of cylinder = 2πr (h + r) sq.
Q. What is the curved surface of cylinder?
The curved surface of a cylinder is equal to a rectangle whose length is 2πr and whose width is h. Where r = radius of the circular face and h = height of the cylinder. The area of the curved surface = Area of a rectangle =l x w = πdh.
Q. What is the difference between curved surface area and total surface area?
Curved Surface Area (CSA) – It includes the area of all the curved surfaces. Lateral Surface Area (LSA) – It includes the area of all the surface excluding the top and bottom areas. Total Surface Area (TSA) – It includes the area of all the surfaces of the object including the bases.
Q. What is the difference between surface area and volume?
Surface area is a two-dimensional measure, while volume is a three-dimensional measure. Two figures can have the same volume but different surface areas. For example: A rectangular prism with side lengths of 1 cm, 2 cm, and 2 cm has a volume of 4 cu cm and a surface area of 16 sq cm.
Q. How are surface area and volume related?
Surface area to volume ratio can be found easily for several simple shapes, like for example a cube or a sphere. For a cube, the equation for surface area is S=6*L*L, where L is the length of a side. Similarly, the volume of a cube is V =L*L*L.
Q. What units do you use for surface area?
Area is measured is square units. We often use square inches, square feet, square centimeters, or square miles to measure area. A square centimeter is a square that is one centimeter (cm) on each side. A square inch is a square that is one inch on each side (see below).
Q. Can FEET be used for surface area?
Note: if the units were feet for this problem, the answer would be 16 feet squared. Not just 16 feet. When we give the answer for surface area we used squared to indicate that it’s a surface area and not just a straight line.
Q. What is the unit for surface area of a rectangular prism?
square units
Q. What is the formula of total surface area of a cube?
The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube.
Q. What is the formula of cube?
Cube and Cuboid Formulas
Cube | Cuboid |
---|---|
Volume of cube = (Side)3 | Volume of the cuboid = (length × breadth × height) |
Diagonal of a cube = √3l | Diagonal of the cuboid =√( l2 + b2 +h2) |
Perimeter of cube = 12 x side | Perimeter of cuboid = 4 (length + breadth + height) |
Q. What is the math formula?
The formula is a fact or a rule written with mathematical symbols. It usually connects two or more quantities with an equal to sign. When you know the value of one quantity, you can find the value of the other using the formula.
Q. What is total surface area of cylinder?
Total Surface Area of Cylinder The total surface area of a cylinder is equal to the sum of areas of all its faces. The Total surface area with radius ‘r’, and height ‘h’ is equal to the sum of the curved area and circular areas of the cylinder. TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units.
Q. What is the formula of total surface area of a hollow cylinder?
A hollow cylinder is made up of two thin sheets of rectangle having a length and breadth. Also, the radius of both the cylinders can be r1+r2. Therefore, the surface area of the cylinder is equal to the surface area of both the rectangles which is equal to 2π( r1 + r2)( r1 – r2 +h).
Q. How do you solve surface area and volume problems easily?
Tricks to solve Volume and Surface Area Problems
- CUBOID. Let length = l, breadth = b and height = h units. Then.
- CUBE. Let each edge of a cube be of length a. Then,
- CYLINDER. Let radius of base = r and Height (or length) = h. Then,
- CONE. Let radius of base = r and Height = h. Then,
- SPHERE. Let the radius of the sphere be r.
- HEMISPHERE. Let the radius of a hemisphere be r.
Q. Why derivative of volume is surface area?
3 Answers. Maybe first review why the derivative of the volume is the surface area: It’s because 4πr2dr is the incremental change in volume when you increase the radius by dr. It makes sense that 4πr2 is the surface area since the then 4πr2dr is the volume of a spherical shell, which represents the added volume.
Q. How do you find the surface area and volume of a cylinder?
Things to Remember
- Surface area of a cylinder = 2πr2 + 2πrh.
- Volume of a cylinder = πr2h.
- You need to know the radius and height to figure both the volume and surface area of a cylinder.
- Answers for volume problems should always be in cubic units.
- Answers for surface area problems should always be in square units.
Q. How do you convert surface area to volume?
For a cube, the equation for surface area is S=6*L*L, where L is the length of a side. Similarly, the volume of a cube is V =L*L*L. So for a cube, the ratio of surface area to volume is given by the ratio of these equations: S/V = 6/L.
Q. What is the surface area and volume of a sphere?
A sphere is a perfectly round geometrical 3-dimensional object. It can be characterized as the set of all points located distance r (radius) away from a given point (center). A sphere with radius r has a volume of 4 3 π r 3 /frac{4}{3} /pi r^3 34πr3 and a surface area of 4 π r 2 4 /pi r^2 4πr2. …
Q. What is the formula for volume and surface area of a hemisphere?
Base surface area of a hemisphere: Ab = π * r² , Cap surface area of a hemisphere: Ac = 2 * π * r² , Total surface area of a hemisphere: A = 3 * π * r² , Surface to volume ratio of a hemisphere: A / V = 9 / (2 * r) .
Q. What is the surface area and volume of a cube?
So for a cube, the formulas for volume and surface area are V=s3 V = s 3 and S=6s2 S = 6 s 2 .
