A company produces canned tomatoes. They want the height h of each can to be twice the diameter d. Enter an equation for the surface area A of the can in terms of the radius r. If the company wants to use no more than 90 square inches of metal for each can, what is the maximum radius of the can they will produce? Round to the nearest tenth of an inch.

Answer 1

The equation is:

(2×π×r×4r)+(2×π×r^2)= A

The maximum radius of the can they will produce = 1.7 inches
