Step-by-step explanation:
Well, first of when you want to find the volume of the cone you need to have a radius and hieght. And the radius is half the diameter, so divide the diameter into half: 10/2=5 in. and you already have the height so just plug in the numbers.
Formula: V= 

h ---> V= 
(
)(27)
And put the plugged in formula in your calculator and you'll find the answer!
V=706.85
I hope this helped.
