Question

Use the formula to solve the problem. Round to the nearest hundredth.

Volume of a sphere: V = 4/31tr3
Surface area of a sphere: A = 4rtr2
Find the volume of a sphere with a radius of 1 inch.
_____cubic in.

Answer 1

Volume of sphere = 4.186 cubic inches

Explanation:

Radius of sphere = r = 1 inch

Volume of sphere = ?

The formula used is:
`Volume\:of\:sphere=(4)/(3)\pi r^3`

Putting value of radius and π and finding volume:

`Volume\:of\:sphere=(4)/(3)\pi r^3\\Volume\:of\:sphere=(4)/(3)* 3.14* (1)^3\\Volume\:of\:sphere=(4)/(3)* 3.14* (1)^3\\Volume\:of\:sphere=4.186 \:cubic\:in`

So, Volume of sphere = 4.186 cubic inches
