Q13 of 63 Page 20

The volume of a right circular cone is 9856 cm3. If the diameter of the base is 28 cm, find :

(i) height of the cone


(ii) slant height of the cone


(iii) curved surface area of the cone.

We have,


Volume of right circular cone = 9856 cm3,


Radius of cone = 14 cm



h = 48 cm


slant height l = = = 50 cm


Curved Surface area of cone = πrl =
