Nigeria is located 5,527.47 mi (8,895.61 km) south of the North Pole. Nigeria is 690.93 mi (1,111.95 km) north of the equator, so it is located in the northern hemisphere.

GPS Coordinates of Nigeria Nigeria has a latitude of 9.0820° N and a longitude of 8.6753° E. These coordinates place Nigeria in both the northern and the eastern hemispheres.

Since Nigeria’s coast lines lies just north of the equator, it can be said that Nigeria is in the northern hemisphere.

Hemisphere is defined as half of the world, globe or brain. An example of hemisphere is the southern part of the world. An example of hemisphere is the left side of the brain. One half of a sphere, formed by a plane that passes through the center of the sphere.

Surface area (TSA) = CSA = 4πr2. Hemisphere : Curved surface area(CSA) = 2 π r2. Total surface area = TSA = 3 π r2.

The curved surface area of a cylinder is defined as the area of its curved surface or the area obtained after excluding the area of its two circular bases. The CSA of cylinder having its base radius ‘r’ and height ‘h’ is given by: Curved surface area (CSA) of cylinder = 2πrh sq. units.

Curved Surface Area- The curved surface area is defined as the area of only curved surface, leaving the circular top and base. Total Surface Area- It is the area of the curved surface as well as the bases. Formula for calculating the Curved Surface Area (C.S.A.)-

To calculate the surface area of a cylinder, you need to find the Base Area (B) and Curved Surface Area (CSA). Therefore, the surface area or the total surface of a cylinder is equal to the sum of the base area times two and the area of the curved surface.

Cross-Sectional Area of a Rectangular Solid The volume of any rectangular solid, including a cube, is the area of its base (length times width) multiplied by its height: V = l × w × h. Therefore, if a cross section is parallel to the top or bottom of the solid, the area of the cross-section is l × w.

The cross-sectional area is the area of a two-dimensional shape that is obtained when a three-dimensional object – such as a cylinder – is sliced perpendicular to some specified axis at a point. For example, the cross-section of a cylinder – when sliced parallel to its base – is a circle.

There is a predefined set of formulas for the calculation of curved surface area and total surface area of a cone, which is collectively called a cone formula. Where, r is the base radius, h is the height and l is the slant height of the cone….Cone Formula.

As we know that the curved surface area (C.S.A) of the right circular cone is πrl. Where, l = slant height of the cone. r = base radius of the cone. Now it is given that the height (h) of the cone is 15 cm and the diameter (d) of the cone is 16 cm.

Definition: The distance from the top of a cone, down the side to a point on the edge of the base. The slant height which is the distance from the top, down the side, to a point on the base circumference. …

The Curved surface area of cuboid is the sum of the areas of its six faces. The surface area is the total area of all the faces of a 3D shape. CSA of a cuboid is calculated using the given Curved Surface Area (CSA) Of Cuboid Formula. First add both length and breadth, then multiply by 2 with Height.
