5 Select the correct answer.

Jack knows the surface area of a cylinder and its radius. He wants to find the cylinder's height. He needs to rewrite the formula A = 2pi r(r+h)
to find the cylinder's height (h) in terms of the cylinder's surface area (A) and its radius (r). Which is the correct formula?
A. h= r+A/2pi r
В. h= A/2pi r
C. h= A/2pi r-r^2
D. h=A/2pi r -r
