Surface area of cones quick check

Answer 1

To find the surface area of a cone, you can use the formula:

Surface Area = πr(r + l)

Where:
- π is a mathematical constant, approximately equal to 3.14159
- r is the radius of the base of the cone
- l is the slant height of the cone, which can be found using the Pythagorean theorem: l = √(r^2 + h^2), where h is the height of the cone

Make sure to substitute the correct values for r and h in the formula to find the surface area of a cone.
