A conical tent is to accommodate 11 persons such that each person occupies 4m2 of space on the ground. They have 220 m3 of air to breathe. The height of the cone is

As each person needs 4 m 2 spaces on ground, so 11 persons will need 44 m 2 space on the ground.
Therefore, Area of ground = 44 m 2



⇒ r2 = 14
Each person needs of air
Therefore volume of tent = 220 m3


Volume of a cone



⇒ h = 15cm
