Answer:

14.34mm

Explanation:

The formula for the volume of a sphere = 4/3nr³

where

n = 22/7

r = radius

give the volume of the sphere, we can determine the radius

12345 = 4/3 x 22/7 x r³

12345 = 88/21 x r³

divide both sides by 21/88

r³ = 2945.965909

take the cube root of both sides

r = 14.34 mm
