Janna is using a cone-shaped cup to fill a cylindrical container.

The cup has the same height and radius as the container. How many times will she have to fill the cylindrical container?

A. 1/3
B. 1
C. 2
D. 3

It didn't show the numbers for the radius or anything, I'm not good at these type of questions. Can someone show me how to work it out?

the volume of a pointy thing with straight sides is (1/3) of the volume of something of the same height and base but the base carried up to the top.
So
you need three cone cups to fill one cylinder.
Thank you
You are welcome.
A cylinder‐shaped cup and a cone‐shaped cup both have radii of 3 inches and heights of 5 inches. The volume cone will be
volume of the cylinder.
