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=2πr (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/2Ï€r
b. h= a/2Ï€r
c. h= a/2Ï€r-r^2
d. h= a/2Ï€r-r
