Question

The radius of the base of a cylinder is 27 cm and its height is 33 cm. Find the surface area of the cylinder in terms of π. a. 3,240π cm2 b. 3,300π cm2

c. 3,213π cm2 d. 3,207π cm2

Answer 1

a. 3,240π cm^2

Explanation:

Answer 2

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
