Question

there are 25 persons in a tent which is a conical in shape every person need an area of 4 square metre of ground inside the tent if height of the tent is 18 cm find the volume of the tent explain with description please

Answer 1

total area required = 25 x 4
                             = 100 sq m 
area of circle = 100sqm
   $\pi$r2= 100 m2
volume = 1/3 $\pi$r2 h
            = 1/3 x 100x 18
            = 600m3

Answer 2

Answer:

5.9929 cubic m.

Step-by-step explanation:

Area required by 1 person = 4 sq.m.

Total area required  by 25 persons = $25  \times 4 = 100$

So, The area of circle = 100sqm

 Area of circle = $\pi r^2$

So, $100=3.14 \times r^2$

$\frac{100}{3.14}=r^2$

$\sqrt{\frac{100}{3.14}}=r$

$5.64=r$

Height pf tent = 18 cm = 0.18 m

Volume of tent =$\frac{1}{3} \pi r^2 h$

                        =$\frac{1}{3} 3.14 \times (5.64)^2 \times 0.18$

                        =$5.9929$

Thus the volume of tent is 5.9929 cubic m.
