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:

2πr = 66

πr = 33 m

r = 33

r = m

Volume of cone = πr²h

So now putting the values,

11 x 21 x 6 =  1386 m³
