Question

Help Please . its due in 5 hours and i cant find answers

Answer 1

39 pi cubic inches

Explanation:

The volume of a cone is (1/3)(area of the base)(height).

`V=(1)/(3)Bh`

Find the area of the circular base. The circumference of a circle is
`C=2\pi r`, so

`2\pi r = 6\pi\\\\r=3`

Now that you know the radius of the circular base, you can find its area:

`A=\pi r^2 = \pi(3^2)=9\pi`

The height of the cone is 13. Time to use the volume formula.

`V=(1)/(3)Bh\\\\V=(1)/(3)(9\pi)(13)\\\\V=39\pi`
