Question

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

Answer 1

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
