Question
The radius of a circle is equal to the radius of base of
a cone. If the diameter of the circle is 35 cm and the height of cone is 18 cm, then find the volume (in cm3) of the cone.Solution
Radius of circle = radius of the cone = 35/2 = 17.5 cm Volume of cone = π × (radius2) × (height/3) = (22/7) × 17.5 × 17.5 × (18/3) = (121275/21) = 5775 cm3
