Question

a conical tent is 21 meters height and the diameter of its base is 4 metre if time and sleep in 8 then the average number of cubic Dm of air space per man is __________.A)4400 B) 4800 C) 8800 D) 8400​

Answer 1

Answer:

First we need l ( slant height).

l = under root (h^2 + r^2)

Step-by-step explanation:

Explanation:

We have,

Height of the circular cone= 6m

Diameter of the circular cone= 7m

Radius of the circular cone= 7/2m       [r= 3.5m]

We know that formula of the volume of the cone:

Therefore,

Volume of the right circular cone=

Volume of the right circular cone=

Volume of the right circular cone= (22×0.5×3.5×2)m³

Volume of the right circular cone= 77m³.

So,

This volume is shared by 12 soldiers.

The average cubic meter of airspace required per soldier=

The airspace required per soldier=

The airspace required per soldier=

Thus,

The airspace required per soldier= 6.41m³.
