If the lateral surface of a cylinder is 94.2 cm2 and its height is 5 cm, then find (i) radius of its base (ii) its volume. (Use π = 3.14)


(i) Height (h) of cylinder = 5 cm

Let radius of cylinder be r


CSA of cylinder = 94.2 cm2


2πrh = 94.2


(2 × 3.14 × r × 5) = 94.2


r = 3 cm


(ii) Volume of cylinder = πr2h


= (3.14 × (3)2 × 5)


= 141.3 cm3
