Answer:
r = 3 inches
Step-by-step explanation:
The formula for the volume of a sphere is the following:
V = (4π/3)r^3
You know the volume so plug that in for V:
36π = (4π/3)r^3
27 = r^3 (multiply by 3/4π to get r^3 by itself)
r = 3 (you take the cube root of r and 27 to get the value of r)
Hope this helps :)

Hope this helps!
The formula for a cone is
![v = \pi \times {r}^{2} \times ( \frac{h}{3} )](https://tex.z-dn.net/?f=v%20%3D%20%5Cpi%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20%20%5Ctimes%20%28%20%5Cfrac%7Bh%7D%7B3%7D%20%29)
insert 20 for your height and rearrange the formula to find the radius. Leave a comment if you need more help.
