Question

A basketball has a volume of 5600cm^3. Find it's radius.

Answer 1

with the volume of 5,600cm to the power of 3 the radius would b 11

Answer 2

11

Explanation:

The formula for the volume of a sphere is

`(4)/(3) \pi \: {r}^(3)`

Using this formula we get:

`(4)/(3) \pi \: {r}^(3) = 5600 \\ \pi \: {r}^(3) = 5600 / (4)/(3) \\ \pi \: {r}^(3) = 4200 \\ {r}^(3) = 4200 / \pi \\`

From this we get that r is approximately 11.
