Question

The tennis ball has a radius of 12 cm. Calculate the volume of the tennis
ball.

Answer 1

7234.56
`cm^(3)`

Explanation:

The formula for the volume of a sphere is
`(4)/(3) \pi r^(3)` where r is the radius. Since
`\pi` is irrational (whose digits goes on forever without repeating), we can write it using the first three numbers: 3.14. Then, substiute 12 for r and 3.14 for
`\pi` into the formula, and you’ll get 7234.56. Finally, add the
`cm^(3)` part to it to get the answer: 7234.56
`cm^(3)`

Hope this helps! :)
