Find the radius of a sphere if its volume is 904.32 cubic cm. (π = 3.14)

Given: Volume of the sphere = 904.32 cm3

And volume of the sphere is given by,


Volume = 4πr3/3


We have to find radius (r), so by rearranging the above equation, we get



Substituting values in the above equation, we get



⇒


⇒ r3 = 216


⇒ r = (216)1/3


⇒ r = 6


Thus, radius of sphere is 6 cm.
