Question

Can someone help me?

Answer 1

Exact answer is 10.4ft ... approximation is 12ft

Explanation:

The formula for volume of a sphere is as follows

`v \: = \: (4)/(3) \pi \: {r}^(2)`

Simply plug volume in and solve for r to get the radius

`113.04 = (4)/(3) \pi \: {r}^(2)`

`26.99 = {r}^(2)`

`r = 5.2`

now simply multiply the radius by 2 to get the answer of 10.4ft

if you do the same calculation but switch 113.04 to 120 to do the approximation value you get 12ft
