Question 1117017
Compare two similar cones. The circular base of the first cone has a radius of 7cm. The second cone has a circular base with a radius of 21cm. Calculate the ratio of the radius of the second cone to the ratio of the old cone.

Side note: I am unsure of how to do this problem, I though tI would do 21/7 but that didn't seem right
------------
one of them is 21, the other is 7.
--> ratio is 21:7 or 3:1
