Volume of a cylinder

1. V = A h.
2. Since the area of a circle = π r 2 , then the formula for the volume of a cylinder is:
3. V = π r 2 h.

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

What is the volume of a right cylinder with a circumference of 25π in and a height of 41.3 in? Explanation: The formula for the volume of a right cylinder is: V = A * h, where A is the area of the base, or πr2.

The Earth has a volume of about 1,083,206,916,846 cubic kilometers (259,875,159,532 cubic miles).

Bulk parameters

On the basis of the seismic data, the inner core is estimated to be about 1221 km in radius (2442 km in diameter);, which is about 19% of the radius of the Earth and 70% of the radius of the Moon. Its volume is about 7.6 billion cubic km (7.6 × 1018 m3), which is about 1⁄140 (0.7%) of the volume of the whole Earth.

The Earth’s core is cooling down very slowly over time. The whole core was molten back when the Earth was first formed, about 4.5 billion years ago. Since then, the Earth has gradually been cooling down, losing its heat to space. As it cooled, the solid inner core formed, and it’s been growing in size ever since.

The mantle is the mostly-solid bulk of Earth’s interior. The mantle lies between Earth’s dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth’s total volume.

If we subdivide the Earth based on rheology, we see the lithosphere, asthenosphere, mesosphere, outer core, and inner core. However, if we differentiate the layers based on chemical variations, we lump the layers into crust, mantle, outer core, and inner core.
