Cone Volume Calculator

Compute the volume of a right circular cone from its radius and height, plus slant height and surface area.

Input

Enter the base radius and height to compute a right circular cone volume, slant height, lateral area and surface area.

Base radius r

Height h

Volume

56.548668

Slant height

6.708204

Lateral area

63.223333

Surface area

91.497666

Use the same length unit for all inputs. Volume is in cubic units and areas in square units.

The volume is V = one third times pi times radius squared times height.
The slant height l is found with l = square root of radius squared plus height squared.
Lateral area is pi times radius times slant height, base area is pi times radius squared, and surface area is their sum.
Enter the radius and height in the same length unit. Volume uses cubic units and areas use square units.
Pi is taken as about 3.14159 in the calculation.
