# Find the surface area of a cone that has a radius of 9 m and a slant height of 27 m. Write your answer to two decimal places.

## Question

## Solution 1

The formula for the surface area of a cone is given by:

A = πr(r + l)

where:

- r is the radius of the base of the cone,
- l is the slant height of the cone.

Given that r = 9 m and l = 27 m, we can substitute these values into the formula:

A = π * 9 * (9 + 27)

Solving this gives:

A = π * 9 * 36 Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
