Question
The height of a right circular
cone is 18 cm. If the volume of the cone is 4158 cm³, find the ratio of the height of the cone to the radius of the cone. (Take π = 22/7)Solution
ATQ, Let the radius of the cone be 'r' cm. Volume of cone = (1/3) × (22/7) × r² × height ATQ: 
The required ratio of height to radius: Ratio = 18:14 = 9:7
