Answer 2

Answer:

The volume of a cone is 28.49 m³ .

Step-by-step explanation:

Formula

$Volume\ of\ a\ cone = \pi r^{2} \frac{h}{3}$

Where r is the radius and h is the height .

As given

In a field,dry fodder for the cattel is heaped in a conical shape.

The height of cone is 2.1 m,and diameter of base is 7.2m.

$Radius = \frac{Diameter}{2}$

$Radius = \frac{7.2}{2}$

Radius = 3.6 m

Height = 2.1 m

$\pi = 3.14$

Putting all the values in the formula

$Volume\ of\ a\ cone =3.14\times 3.6\times 3.6\times \frac{2.1}{3}$

$Volume\ of\ a\ cone =\frac{2.1\times 3.14\times 3.6\times 3.6}{3}$

$Volume\ of\ a\ cone =\frac{85.46\ (Approx)}{3}$

Volume of a cone = 28.49 m³ (Approx)

Therefore the volume of a cone is 28.49 m³ .
