yulyashka [42]

Answer:

volume of the cone = 247.98 cubic meter

Step-by-step explanation:

Height of the cone= 11.7 m

Circumference= 9 m

Radius= 9/2= 4.5 m

Volume of the cone;

= $\pi r^2\frac{h}{3}$

As, $\pi =\frac{22}{7}= 3.14$

Putting the values in the formula:

Volume of the cone is:

$=3.14*(4.5*4.5)*\frac{11.7}{3} \\\\=3.14*(4.5*4.5)*3.9\\\\=3.14*20.25*3.9\\\\=3.14*78.98\\\\=247.98m^3$

The volume of the cone is 247.98 cubic meter
