Help with finding the volume of the cone pictured

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 = [tex]\frac{1}{3} \pi r^{2} h[/tex]
[tex]$=\frac{1}{3} \times 3.14 \times 3^{2} \times 6[/tex]
[tex]$=3.14 \times 18[/tex]
= 56.52
Volume of the cone = 56.52 in³
Hence the volume of the given cone is 56.52 [tex]\text{in}^3[/tex].
