Question

Radius of ball is 6in. What is the volume?

Answer 1

Radius of ball is 6 inches. Then the volume is 904.32
`in^3`

Solution:

Given that, radius of a ball is 6 inches.

We have to find the volume of the ball with 6 inches radius.

Now, we know that, a ball will be in a shape of sphere, so we have to use the volume of a sphere formula to find the volume of the ball.

The volume of sphere is given as:

`\text { volume of sphere }=(4)/(3) \pi r^(3)`

where r is the radius.

Here in our problem, r = 6

`\text { Then, volume }=(4)/(3) * \pi * 6^(3)`

`\begin{array}{l}{=(4)/(3) * \pi * 6 * 6 * 6} \\\\ {=4 * \pi * 2 * 6 * 6} \\\\ {=8 * \pi * 36} \\\\ {=288 \pi=288 * 3.14=904.32}\end{array}`

Hence the volume is 904.32
`in^3`
