Question

21) A conical tent is 18 m high and the circumference of its base is 88 m. The volume of air in it will be:
(A) 1275 m3 (B) 1836 m3 (C) 2430 m3 (D) 3696 m3
(E) None of these​

Answer 1

Answer:

(e)

Step-by-step explanation:

Answer 2

volume of cone= pir^2h/3

height=18

circumference =2pir=88

radius =88/2pi

now

volume=

pi × (88/2pi)^2 ×18/3

=3696.. (e)
