Question

The surface area of a cone is found using the formula S.A. = 3.14r^2+3.14rl. Describe what each part of the formula represents and how these parts are used to calculate the surface area.

Answer 1

1. Based on the information given in the problem above, you can calculate the surface area of a cone by using the formula:

`S.A. = 3.14r^(2)+3.14rl`

2. The term
`3.24r^(2)` represents the area of the base of the cone, which is a circle.

3. The other term
`3.14rl` represents the lateral surface area of the cone, where
`l` is the slant heigth:

Therefore the answer is:
`3.14r^(2)` is the area of the base of the cone and
`3.24rl` is the lateral surface area of the cone.
