Radius of the base of cylinder r = 27cm
height of the cylinder h = 33cm
Surface area of the Cylinder = Area of two base circles + Area of rolled

rectangle
SA of cylinder = Ď€r^2 + Ď€r^2 + 2Ď€rh = 2Ď€r^2 + 2Ď€rh = 2Ď€(r^2 + rh) 
SA = 2Ď€(27^2 + (27 x 33)) = 2Ď€(729 + 891) = 3240Ď€
SA of cylinder = 3240Ď€ cm

Answer

a. 3,240π cm^2
