how do we calculate Surface Area of a Cylinder?

 To find the Surface Area of a cylinder you would use the formula
                                                             S.A.= L.A. + 2B

To find Lateral Area ( L.A.) you would use the formula
                                                               L.A.= 2πrh

One you get the lateral area you plug that number into the SA formula. The next step, you would have to find the area base of the base to plug it into the SA formula.
                                       Area of base= πr2
