Answer 2

Answer:

Step-by-step explanation:

Amount of area reqd. by 1 person to stand = 6 sq.metre

Amount of area reqd. by 10 person to stand = 6x10 sq.metre i.e 60 sq.metre

So,

Base Area, pi*r*r=60

=>r*r = 60/pi ---------------(1)

Now,

Volume of air reqd. to breathe 1 person= 60 cu.metre

Volume of air reqd. by 10 person to breathe = 60x10=600 cu.metre

So,

Volume, 1/3*pi*r*r*h = 600 ---------------------(2)

Putting the value of eqn 1 in eqn 2, we get

1/3*pi*60/pi*h = 600

==> 1/3*60*h = 600

==> 20*h = 600

==> h = 600/20 = 30

Therefore height = 30 metres
