Question 914662: HI,
I have tried everything and I just cannot grasp this and it is due tomorrow.
1) The surface of af a cylinder is given by the formula A= 2 (pi) to the second power. + 2 (pi) r, h. Where is h is the height and and tyhe cylinder and r is the raduis of it's base. Express the height from the formula (solve for h) Please helpa nd thank you

The entire formula for the surface area of a cylinder is
A=2pi%2A+r%5E2+%2B+2pi%2Ar%2Ah+
to solve for h move all other terms to the other side of equal sign

A-2pi%2Ar%5E2=+%282pi%2Ar%29+h+

%28A-2pi%2Ar%5E2%29%2F%282pi%2Ar%29=++h+
