A conical tent is to accommodate 11 persons. Each person must have of the space on the ground and of air to breath. Find the height of the cone.

Given,


Number of person in the room = 11


Each person covers area = 4m2


Total area covered by all = 44m2


πr2 = 44



Volume of the cone = 220m3


We know that,


Volume of the cone =





Hence, the height of the cone will be 15m
