Volume of a Sphere
V = (4/3) π r ³
r ³ = (3 V) / (4 π)
r = (3 V / 4 π)^(1/3)
Volume of a Cylinder
V = π r ² h
r ² = V / (π h)
r = √ (V / π h)

Nicole...you must specify the volume area you are looking for. A spehere, a cylinder?
For example, the volume of a sphere is given as 4/3 pi(r^3)
so the radius is givem as
V(3/4)*1/pi = r^3
or r = [3V/(4pi)]^(1/3)
hope this information helps!

FOR A BALL:
C=2 pie r
V=4/3 pie r(to the 3rd)
hope this helps???

That depends on what shape you are working with
sphere r= (3V/(4Ï))^1/3
cylinders r= [V/(Ïh)]^1/2

given volume of sphere
V = (4/3) pi r^3
r^3 =3V/(4pi)
r = [ 3V/(4pi) ]^(1/3)

since v=pie*r squared*height
then r squared=v/pie*height
thus r=square root of (v/pie*height)
/ =division
* =multiplication

depends on what the object is...(sphere, cone, cyliner??)
