Q1 of 52 Page 145

Find the volume of a cone if the radius of its base is 1.5 cm and its perpendicular height is 5 cm.

Radius of base of cone, r = 1.5cm


Perpendicular height of cone, H = 5cm


As we know that,


Volume of the cone,


On substituting the given values,



⇒ V = 11.79 cm3


∴ Volume of the cone is 11.79 cm3
