The height of the cylinder is 4 inches.
A. Find the inverse function to A(r). your answer should look like r = "some expression involving A"
r(A) =
Hints: to calculate an inverse function, you need to solve for r.
here you could start with A=2(pi)r^2+8(pi)r. this equation is the same as
2(pi)r^2+8(pi)r-A = 0 where the variable x is r?
you can solve for r using the quadratic formula even though the constant term c is a symbol here
I am stuck, and cannot figure this out.
