A cylinder with a diameter of 2cm has a volume of 15.7cm^3. what is the height of the cylinder?

To calculate volume of cylinder is used the formula v=pi. (r^2). h where h is height now just do a simple equation. 15.7 = 2pi. h since r^2 is diameter then 2pih = 15.7 then pass 2pi dividing and we get h = 15.7/2pi that gives approximately 2.49cm
