# Surface Area Of A Right Cone Calculator

The Surface Area of a Right Cone Calculator is an online tool that helps us find the value of Surface Area when we know the radius of the right cone's circular base and its slant height. The surface area calculator for right cone on BYJU makes math easy and fun.

All things in our universe have a weight, and we measure this in Kilograms and Pounds. To do work in the international space or in laboratories, we have to convert Pounds to Kilograms. The conversion rate is 1 Pound = 0.453592 Kgs.

Formula:
The area of the right cone is equal to r(r + l).
where r is the diameter of the base.
l is the height of the slope

What is the right cone's surface area?
A right cone is one whose point is right in the middle of its round base. It means that the line from the cone's point to its base goes through the middle. A cone is a three-dimensional shape that has both a surface area and a volume.

The area covered by the outside of a right circular cone is its surface area. It is equal to the area of the circle's base plus the area of the sides.

Surface area (right cone) = Area of round base plus area of curved surface
SA = π r2 + π r l
SA = π r (r + l)
r is the radius and l is the slant height.
