We must now make the cylinder's height 2r so the sphere fits perfectly inside. The volume of the cylinder is: π × r2 × h = 2 π × r3. The volume of the sphere is: 4 3 π × r3. So the sphere's volume is 4 3 vs 2 for the cylinder. Or more simply the sphere's volume is 2 3 of the cylinder's volume!To calculator the volume of a slanted cylinder: Find the radius, side length, and slant angle of the cylinder. Square the radius.
