The program is designed to calculate the area of ​​the full surface of the cone and the area of ​​the lateral surface of the cone.

A cone is a geometric body that is formed by the rotation of a right triangle around one of its legs.

The area of ​​the lateral surface of the cone is equal to the product of the number π by the radius of the circumference of the base and the length of the generatrix of the cone.

Formula of the cone lateral surface area:


where r is the radius of the circumference of the base,
l is the length of the generatrix of the cone.

The area of ​​the full surface of the cone is equal to the sum of the areas of the base of the cone and its lateral surface. The basis of the cone is a circle.

The formula for the total surface area of ​​a cone is:


where r is the radius of the circumference of the base,
l is the length of the generatrix of the cone.

To find the area of ​​the side surface of the cone and / or the area of ​​the full surface of the cone, enter the value of the radius of the base of the cone and the value of the length of the generatrix of the cone and click the "CALCULATE" button.

The program will determine the area of ​​the lateral surface of the cone and / or the area of ​​the full surface of the cone.

The source data and the result of the calculations can be copied to the clipboard for further use in other applications.
