A Conical tent was erected by the army at a base camp with height 3 m and base diameter 10 m. If every person requires 3.92 cu.m air, then how many persons can be seated in that tent approximately?

Correct Answer: 20

Explanation:

Given height of the conical tent = 3 m


Diameter = 10 => Radius = D/2 = 10/2 = 5 m 


Now, as the tent is in the conical form


Volume of the conical tent =  π r 2 h 3  


=> (22 x 5 x 5 x 3) / (7 x 3) 


= 22 x 25/7 


= 78.54 cu.m 


Given each person requires 3.92 cu.m of air 


=> Number of persons can be seated in the tent = 78.54/3.92 = 20.03 =~ 20
