Surface Area of Cones (Jump to: Lecture | Video )

Figure 1.

Above we have a representation of a cone. How do we find its surface area?

Surface Area of a Cone
The surface area of a cone is found by the equation:

Surface Area = (3.14 * 5 * 8) + (3.14 * 5^2)

Surface Area = 125.6 + 78.5

Surface Area = 204.1
