# Calculator for Total Surface Area of a Cone

This calculator will help you find the surface area of a cone. The formula used in this calculator is listed below.

To use this calculator, you will need to know the radius and outer length.

To give you a better mental model of the cone, you can look at the visualization below. You can navigate the 3d-model of the cone as you like.

## Results

Surface Area = **628.319**

## Cone Surface Area Formula

Formula variable explanation:

- C represents the surface area.
- r represents the Radius.
- l1 represents the Outer length.

### LaTeX formula

If you are working in a TeX based editor you could use this TeX formula to calculate the cone surface area.

\mathrm{C}=\pi\cdot r\cdot\left( l1+ r\right)

## How To Calculate The Cone Surface Area Your Self

Calculating the surface area is rather simple when you know the formula presented above. Follow these steps:

**Then change the following variables with your values:**

**r** shall be changed with the *Radius* of your cone. As an example **r** could be changed to 10.**l1** shall be changed with the *Outer length* of your cone. As an example **l1** could be changed to 10.

- Now you can enter this in to your calculator and you will get your answer.
