Can someone help me?

Answer 1

Answer:

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

Step-by-step explanation:

The formula for volume of a sphere is as follows

$v \: = \: \frac{4}{3} \pi \: {r}^{2}$

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

$113.04 = \frac{4}{3} \pi \: {r}^{2}$

$26.99 = {r}^{2}$

$r = 5.2$

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
