What is the surface area of the cone? Use 3.14 for pi and round to the nearest tenth, if necessary.

1 answer

To calculate the surface area of a cone, you need to know the value of the radius and the slant height. If you have the radius and height of the cone, you can use the formula:

Surface Area = π * r * (r + l)

Where:
- π is a mathematical constant approximately equal to 3.14
- r is the radius of the cone
- l is the slant height of the cone, which can be found using the Pythagorean theorem: l = sqrt(r^2 + h^2), where h is the height of the cone.

If you can provide the radius and height of the cone, I can calculate the surface area for you.
