anonymous one year ago The volume of a cone that fits exactly inside a cylinder is 15 cubic feet. What is the volume of the cylinder? (5 points) 45 cubic feet 75 cubic feet 225 cubic feet 1500 cubic feet

Compare the two volume formulas: $V _{cylinder}=\pi r^2h$ $V _{cone}=\frac{1}{3}\pi r^2h$

I don't know how to find the radius or the height

4. Mertsj

If the volume of the cone is exactly 1/3 the volume of the cylinder, what should you do to the volume of the cone to get the volume of the cylinder?

5. anonymous

Multiply it by 3?

6. Mertsj

Very good!!!

So multiply 15 by 3?

9. Mertsj

That's what you said.

10. anonymous

ok so it would be 45 then, right?

11. Mertsj

yep

12. anonymous

ok thx that was easier than I thought.
