Geometry: need help finding volume of cone

[From: ] [author: ] [Date: 12-05-17] [Hit: ]
How do i find the radius?-Use the pythagorean theorem to find the radius, because you have one leg, and the hypotenuse for a right triangle.Thats the radius, so now you have all the information needed to find the volume.......
The formula to find the volume of a cone is
1/3 X pie X radius (squared) X height.
I am given that slanted height of a cone is 17 and the height is 15, but i am not given the radius. How do i find the radius?

Use the pythagorean theorem to find the radius, because you have one leg, and the hypotenuse for a right triangle.

a^2 + 15^2 = 17^2
a^2 = 289-225= 64
a= 8

That's the radius, so now you have all the information needed to find the volume.
