Cone Surface Area Calculator

The Cone Surface Area Calculator allows you to quickly determine the total surface area of any cone. Perfect for students, designers, and engineers, it turns complicated geometry equations into straightforward, precise, and rapid answers.

What is a Cone?

A cone is a three-dimensional geometric shape that tapers smoothly from a flat circular base to a single top point called the apex.

Key elements of a cone:

• Radius (r): Distance from the center of the base to its edge.
• Slant Height (l): The diagonal distance from the apex to any point on the circular edge.
• Height (h): Perpendicular distance from the apex to the center of the base.

Formula for Surface Area of Cone

$$\text{TSA}=\pi r(r+l)$$

This expands to:

$$\text{TSA}=\pi r^2+\pi rl$$
