Please help meee!!! 5 stars to the best answer.

Answer 1

Answer:

3 cm

Step-by-step explanation:

First, find the volume of the cone.

V = $\frac{1}{3}$$\pi$r²h

V = $\frac{1}{3}$(3.14)(9)(12)

V = 113.04

This means the sphere is also 113.04

Use the formula V = $\frac{4}{3}$$\pi$r³

113.04 = $\frac{4}{3}$(3.14)r³

113.04 = 4.19r³

26.98 = r³

3 ≈ r
