Question
The volume of cone is 1900.8 cm3. If its
height is 1.4 cm then find the radius of the cone.Solution
Let the radius of the cone be βrβ cm Therefore, (1/3) Γ (22/7) Γ r2 Γ 1.4 = 1900.8 Or, r2 = 1900.8 Γ (7/11) = 1296 Or, r = 36 (since, radius cannot be negative) Therefore, radius of the cone = 36 cm
