Question

Use the image to answer the question.

A cone shows a radius of 6 and hypotenuse or side as 11.

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

Answer 1

Surface area = πr^2 + πrl = πr(r + l) = 3.14·6·(6+11) = 3.14·102 = 320.28 ≈ 320.3

So the surface area is 320.3 square units.
