Answer:
39 pi cubic inches
Step-by-step explanation:
The volume of a cone is (1/3)(area of the base)(height).
Find the area of the circular base. The circumference of a circle is , so
Now that you know the radius of the circular base, you can find its area:
The height of the cone is 13. Time to use the volume formula.
