Question 723338
The formula for the volume of a sphere is {{{v=4/3pir^3}}}. solve for R the radius of a sphere is {{{r= cube sqrt 3v/4pi}}} 
-----
V = (4/3)pi*R^3
pi*R^3 = (3/4)V
----
R^3 = (3V)/(4pi)
----
R = cbrt[(3V)/(4pi)]
============================

if the volume of a sphere is {{{20ft^3}}}, what is the radius of the sphere to the nearest hundredth
R = cbrt[(3*20)/(4pi)]
----
R = cbrt[15/pi]ft.
=========================
