Question

the circumference of the base of a 12 m high conical tent is 66 m. find the volume of air contained in it. ​

Answer 1

Answer :

132cm.sq.

Step-by-step explanation:

circumference of circular base of conical tent = 66m [_given]

we know that,

circumference of circle = 2πr

therefore,

66 = 2πr

33 = 22/7 * r

(33*7)/22 = r

(3*7)/2 = r

10.5 cm = r

Now,

Volume of air contained in it = volume of conical tent

therefore,

Volume of air = 1/3πr2h

= 1/3 * 22/7 * 12 * 10.5

Volume of air

Volume of air = 132 cm2

Thus, there is 132 cm.sq. air is present in the conical tent..
