Icona has a diameter of 10 inches, comb b is a diameter of 90 inches.
00:03
Conebs are similar.
00:05
Find the ratio of a to b.
00:09
Currently the ratio is 10 to 50.
00:18
And you can simplify this down.
00:21
I mean, the way to write that, it would be like, it's a fraction 10 over 50.
00:24
Wherever you are, i don't know how you want it.
00:27
You can simplify this down as 1 over 5.
00:30
So this, or 1 5th.
00:33
What these are is this is just the scale factor.
00:39
For like the one dimensional properties of the cone, this would be the scale factor at one -fifth, going from a to b...
