Question

What is the answer to this problem?

Answer 1

`r=(2)/(3)\ yards`

Explanation:

Given that,

The volume of a sphere is,
`V=(32)/(81)\pi` cubic yards

We need to find the radius of the sphere. The formula for the volume of a sphere is given by :

`V=(4)/(3)\pi r^2`

Put all the values,

`(32)/(81)\pi=(4)/(3)\pi r^3\\\\r^3=(8)/(27)\\\\r=(2)/(3)\ yards`

So, the radius of the sphere is equal to
`(2)/(3)\ yards`.
