Okay, so I have a cone that has the following measurements:The radius is 3 and the height is 4.


How do I find the slant height? (Would I also use the same method to find the height or radius in another cone as well?)

Would it work to use Pythagorean Theorem or is there some other method since the other angle measures are not given?
 
Other trig functions could be used, but why? You should find the Pythagorean Theorem sufficient.

I was only wondering if I needed to do it by a trig function cause I was suppose to be using trig to find the volumes of right cones and regular pyramids. Thank you for the help.

No harm. No foul. Feel free to explore and find other solutions. Unique answers don't care how you find them. :D

Good work.
