what is the volume of this cone?

Answer:
3537.73 cubic in
Step-by-step explanation:
Given,
Diameter of the cone = 26 in
Radius of the cone = 26in ÷ 2 = 13 in
Height of the cone = 20 in
Therefore, volume of the cone
[tex] = \frac{1}{3} \pi {r}^{2} h[/tex]
[tex] = \frac{1}{3} \times 3.14 \times 13 \times 13 \times 20[/tex]
[tex] = 3,537.7333333333 \: {in}^{3} [/tex]
Approx. 3537 . 73 cubic in (Ans)
