Question

The circumference of the base of a 12m high conical tent is 66m .Find the volume of air content in it .​

Answer 1

Answer:

Circumference of base =66m

Hight of tent=12m

Circumference of circle= 2πr

66=2×22/7×r

66×7/2×22=r

r =10.5m

Volume of come =1/3πr^2h

=1/3×22/7×10.5×10.5×12

=1386m^3

Answer 2

Answer:

2πr = 66

πr = 33 m

$\frac{22}{7}$ r = 33

r = $\frac{21}{2}$ m

Volume of cone = $\frac{1}{3}$πr²h

So now putting the values,

$\frac{1}{3} X \frac{22}{7} X \frac{21}{2} X \frac{21}{2} X 12$

11 x 21 x 6 =  1386 m³
