Question

A cone has a slant height that measures 24 feet and a radius that measures 13.5 feet. What is the surface area of the cone?

1. Apply the surface area formula: SA = πr2 + πrl

2. Substitute measures into formula: SA = π(13.52) + π(13.5)(24)

3. Evaluate the power and multiply: SA = 182.25π + 324π

4. Add to simplify: SA =
btw the answer is 506.25πft2 actually .

Answer 1

2. Substitute measures into formula: SA = π(13.52) + π(13.5)(24)

yeah
