Radius of the sphere
V = (4/3) π r³r — radius. Cube the radius, multiply by π and 4/3.
Surface area = 4πr² (different formula)
Calculate the volume of any cylinder using radius and height.
Calculate cube volume for boxes, containers, blocks, classroom models, and any shape where all edges are the same length.
Next: ellipsoid volume.
