Hi, I'm trying to figure out a problem for homework and I don't
understand how to any of this so if you can place help me I would
really appreciate it!
The direction is to find the surface area of the cone. Now I have the cone drawn in my book. I know all the
formulas and everything but I just don't understand how to find the
slant height of this cone. The height is 40 and the radius is 9. How
do I find the slant height of this??
Oh and also I have a formula when trying to find the volume of a cone:
V=B(the area of the base) X h. Now I need to find a volume of a cone
with a radius of 7 and height 45. How do you get the B?
Thank you so much for your help!
