Question
how do i find the radius of a sphere with the volume= 4.5pie

Answer
Volume of a sphere =(4/3)*pi*r3

So just fill in what you know and solve for r (radius)

4.5pi = (4/3)*pi*r^3 multiply both sides by 3
3(4.5)pi = 4pir^3  divide both sides by pi
3(4.5) = 4r^3
13.5 = r^3  take the cube root of both sides (need calculator)
r = 2.38
