Question 995771: The formula A = 2πrh tells us the lateral surface area A of a cylinder with radius r and height h.
a) Solve the formula for radius, r.
b) Use the new version of the formula to find the radius of a can that has lateral surface area 301.44 square inches and height 12 inches. Use 3.14 as an approximation for π.

The formula A = 2πrh tells us the lateral surface area A of a cylinder with radius r and height h.
a) Solve the formula for radius, r.
A+=+2pi%2Ar%2Ah
Divide by 2pi*h}}}

b) Use the new version of the formula to find the radius of a can that has lateral surface area 301.44 square inches and height 12 inches. Use 3.14 as an approximation for π.
