Answer :

Let r be the radius of base and h be the height of cylinder


Curved surface area of cylinder = 660 cm2


Curved surface area = 2πrh


2πrh = 660


2 × × r × h = 660


r × h =


r × h =


r × h = 15 × 7


r × h = 105


rh = 105


Volume of cylinder = 1650 cm3


Volume of cylinder = πr2h


πr2h = 1650


× r × r × h = 1650


Using r × h = 105 we get


× r × 105 = 1650


22 × 15 × r = 1650


r =


r =


r = 5 cm


Substitute r = 5 in r × h = 105 to get h


5 × h = 105


h =


h = 21 cm


Therefore, radius is 5 cm and height is 21 cm
