# Surface Area of a Cone Calculator

A cone is a three-dimensional geometric shape that tapers from a flat circular base to a point at the top called the apex or vertex. The surface area of a cone is a measure of the total area that the surface of cone occupies. In the right circular cone calc, find A by entering radius and height as inputs and click calculate. Make use of this simple online surface area of a cone calculator to calculate the total surface area(TSA) of a circular cone.

Code to add this calci to your website

#### Formula:

t = π × r × ( l + r )
l = √(r^{2} + h^{2})
**Where,**
t = Total Surface Area
r = Radius
h = Height
l = Slant Height

#### Example

**
A cone has a radius of 5 cm and height of 8cm. Find Total surface area?**

l =√(5 + 8)

=√89

=9.43 cm

t =3.14 × 5 × 14.43

=93.31 cm^{2}
