Question

Which expression gives the volume of a sphere with radius8?

Answer 1

`(4)/(3) * \pi * 8 * 8 * 8`

Answer 2

`V=(4)/(3)(8)^(3)\pi`

Explanation:

The formula for calculate the volume of a sphere is shown below:

`V=(4)/(3)r^(3)\pi`

Where V is the volume of the sphere and r is the radius of the sphere.

The problem says that the radius of the sphere is 8. Then, you only need to substitute this value into the formula shown above.

Therefore, you can calculate it as following:

`V=(4)/(3)(8)^(3)\pi=2144.66`
