Surface Area of a Cone Calculator

Work out the surface area of a cone.
Two cone surface area calculators based on radius or diameter and height.

Cone Surface Area Formula

Cone Surface Area = pi x radius squared + pi x radius x square root (radius squared + height squared)
Cone Surface Area = π r² + π r √ (r² + h²)
If inputs are in centimetres then the results are in square centimetres.
If inputs are in inches then the results are in square inches.
If inputs are in metres then the results are in square metres.
If the inputs are in feet then the results are in square feet.

• A cone is a type of geometric figure with the shape of a circular base which tapers to a point called its apex
• To find the surface area for a cone, use this formula when given the radius and diameter as your two measurements
• The top calculator will find the cone surface area from radius and height
• The second calculator will find the cone surface area using diameter and height
• Input units will result in input unit square output
