Question

The circumference of the base of a 9m
high wooden solid cone is 44 M find the volume of air contain in it

Answer 1

$\textbf {Question}$ :

The circumference of the base of a 9m high wooden solid cone is 44m. Find the volume of air contained in it.

$\textbf {Answer}$ :

h = 9 m

2πr = 44

2 × 3.14 × r = 44

r ~ 7cm

Volume of a cone = (πr^2h)/3

=(3.14×49×9)/3

=461.58 cubic meters (approx.)

Answer 2

Answer:

Step-by-step explanation:

Given,

Circumference of the base of the cone is 44 m

hence,

2πr=44 m

2×22/7×r = 44 m

r = 44×7/44 m

hence, r=7 m(radius of base of cone.)

Now,

The volume of cone is given by

1/3πr^3

1/3×22/7×[7]^3

22×49/3

359.33 m ^3
