Respuesta :
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 = πr^2 + πr^2 + 2πrh = 2πr^2 + 2πrh = 2π(r^2 + rh)
SA = 2Ď€(27^2 + (27 x 33)) = 2Ď€(729 + 891) = 3240Ď€
SA of cylinder = 3240Ď€ cm
