Help with finding the volume of the cone pictured

jasenka [17]

Volume of the cone = 56.52 in³

Solution:

Diameter of the cone = 6 in

Radius of the cone = 6 ÷ 2 = 3 in

Height of the cone = 6 in

The value of π = 3.14

To find the volume of the cone:

Volume of the cone = $\frac{1}{3} \pi r^{2} h$

$$=\frac{1}{3} \times 3.14 \times 3^{2} \times 6$

$$=3.14 \times 18$

= 56.52

Volume of the cone = 56.52 in³

Hence the volume of the given cone is 56.52 $\text{in}^3$ .
