Question

4. A conical tent is required to accommodate 5 people ; each person must have 16 sq. metre of space on the ground,
and 100 cu. metre of air to breath; give the vertical height of the tent.
​

Answer 1

Step-by-step explanation:

total area of conical base = 5×16 = 80 m²

volume of the conical tent = 5 × 100 = 500 m³

to find height h ?

base area = πr² = 80

Volume of tent V = 1/3πr²h

500 = 1/3*80"h

=> h = 500*3 / 80

=> h = 100/8

=> h = 12.5 metres
