Question

what is the approximate volume of the cone with the height of 12 in. and radius of 9 in.??
Use 3.14 for pi

​

Answer 1

Answer:

1,017.36 cubic inches

Step-by-step explanation:

The volume of the cone is found using the volume formula for a cone $V=\frac{1}{3}\pi r^2h$.

Substitute h=12 and r = 9.

$V = \frac{1}{3}\pi r^2h\\V = \frac{1}{3}\pi (9^2)(12)\\V=\frac{1}{3}\pi *81*12\\V = \frac{972}{3}\pi \\V= 324\pi =1,017.36$
