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 =
