Surface Area of a Cylinder h A cylinder is a prism with a circular cross-section. 2r2r

4
Surface Area of a Cylinder A cylinder is a prism with a circular cross- section. r2r2 r2r2 Removing top and bottom Open out 2 r h Surface Area = 2 r 2 + 2 rh = 2 r(r + h)

5
Surface Area of a Cylinder 8cm Surface area = 2 r(r + h) 3cm Find the surface area of the cylinder. SA = 2 x x 3(3 + 8) = 6 x 11 = 66 = 207 cm 2 (3 sf)

6
6 cm The Surface Area of a Cylinder Calculate the surface area of the following cylinders. 15 cm 2.1mm 9.2 mm 3 cm 2 m 1 2 3 SA = 2 x x 3(3 + 6) = 6 x 9 = 54 = 169.6 cm 2 SA = 2 x x 2(2 + 15) = 4 x 17 = 68 = 213.6 m 2 SA = 2 x x 4.6(4.6 + 2.1) = 9.2 x 6.7 = 193.6 mm 2 2 r(r + h)
