Q4 of 189 Page 500

The circumference of the base of a cone is 44 cm and its slant height is 25 cm. Find the volume and curved surface area of the cone.

Given,


Circumference of the base of the cone = 44cm


2πr = 44cm



r = 7cm








= 22 × 56 = 1232


Volume = 1232 cm3


Curved surface area = πrl



= 550 cm2
