Calculate the volume of a cone from its base radius and vertical height. A cone holds exactly one third of the cylinder that shares its base and height, so the volume is one third times pi times the radius squared times the height. For a radius of 3 and a height of 4, the volume is about 37.7 cubic units. This calculator also computes the slant height, which is the straight distance from the base edge up to the tip found with the Pythagorean theorem, and the total surface area that adds the circular base to the curved side. Cones describe ice cream cones, funnels, party hats, traffic cones and piles of sand. Enter the radius and height in a common unit and the volume returns in that unit cubed while surface area is in the unit squared. All of the geometry runs locally in your browser at full precision, and the volume copies with a single click.
The volume is one third of pi times the radius squared times the height, a third of the matching cylinder.
The slant height runs from the tip down to the edge of the base and equals the square root of the radius squared plus the height squared.
It sums the circular base and the curved side, using the slant height for the sloped surface.
