Answer:
Radius is 2.54 so its base is 5.08
Step-by-step explanation:
The volume of the cone is found using the volume formula for a cone [tex]V=\frac{1}{3}\pi r^2h[/tex].
Substitute V = 15pi and h=7.
[tex]V = \frac{1}{3}\pi r^2h\\ 15\pi = \frac{1}{3}\pi (r^2)(7)\\15=\frac{1}{3} r^2*7\\45 = 7r^2 \\6.42 = r^2 \\ 2.54 = r [/tex]
