62.8 (pi times radius squared times height (3.14* 2 squared=12.56 then 12.56 times 5= 62.8)
Since the formula for the volume of a cylinder is PI time the radius squared times the height we can calculate the height from the other two values. The height is the volume divide by PI times the radius squared.
1/3 pi times radius squared times height
The formula for area of a circle is radius squared times pi. The formula for volume of a cylinder is radius squared times pi times height.
The volume of a cylinder is simply the area of the circular base times the cylinder's height. Volume of a cylinder = ╥ r² h (pi x radius squared x height) ╥ (Pi) ≈ 3.14 r = radius of the base circle, and h = height of the cylinder --- V= pi r squared times height Volume in cubic units = pi*radius2*height
