Height of the cylinder (h) = 5 cm Let r сm be the radius of the base Lateral surface area of cylinder = 94.2 cm2 ⇒ 2 πrh = 94.2 cm2 2 x 3.14 x r x 5 = 94.2 ⇒ r = 94.2/2 x 3.14 x 5 = 94.2/31.4 = 3 cm Thus, radius of the base of cylinder = 3 cm. (ii) Volume of cylinder = πr2h = 3.14 x 32 x 5 = 141.3 cm3
