Calculate the volume of a cone instantly with this free interactive 3D calculator. The formula is V = (1/3)πr²h, where r is the radius of the circular base and h is the perpendicular height. A cone has exactly one-third the volume of a cylinder with the same base and height. Enter your values in the panel and watch the 3D model update in real time.

Use this tool for real-world calculations: find the volume of ice cream cones, funnels, party hats, conical storage tanks, or piles of sand and gravel. For example, a cone with radius 3 cm and height 8 cm has a volume of approximately 75.4 cm³. The calculator also shows the slant height and surface area.
