Can someone help me?

Answer:
Exact answer is 10.4ft ... approximation is 12ft
Step-by-step explanation:
The formula for volume of a sphere is as follows
[tex]v \: = \: \frac{4}{3} \pi \: {r}^{2} [/tex]
Simply plug volume in and solve for r to get the radius
[tex]113.04 = \frac{4}{3} \pi \: {r}^{2} [/tex]
[tex]26.99 = {r}^{2} [/tex]
[tex]r = 5.2[/tex]
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
