330 = (4/3) pi *radius^3       multiply both sides by  3/4

 

330 * 3/4 =  pi * radius^3      divide both sides by pi

 

(247.5) / pi  = radius^3         take the cube root

 

radius ≈   4.29 cm

 

 

30 = (1/3)  pi  radius^2 * 3

 

30 = pi * radius^2              divide both sides by pi

 

30 / pi  = radius^2         take the square root

 

radius   ≈ 3.09 m
