Question

A beach ball has a radius of 1.2 feet. What is the volume of the beach ball? Round to the nearest tenth. I NEED HELP, HELP ME PLEASEEE

Answer 1

7.2 feet

Explanation:

The volume of a sphere is V =
`(4)/(3\\)`
`\pi`
`r^(3)`. In simple terms, you're cubing the radius, multiplying it to pi, and then multiplying 4/3.

Using the formula, we cube the radius of 1.2 feet.

1.2 x 1.2 x 1.2 = 1.728

Then, you multiply 1.728 with pi.

1.728 x
`\pi` = 5.42867210

Afterwards, you multiply 5.42867210 with
`(4)/(3)`.

5.42867210 x
`(4)/(3)` = 7.23822946667

Since the instructions say to round the nearest tenth, it becomes 7.2 feet.
