Thanks Rusty,

I plugged in the cord and height from my tracing into the calculator; it wouldn’t accept .10 in the height, cord was 1.33, so I base 10 the thing and came up with a radius of 7.21 and doubled for a diameter of 14.42” does my math track, or do I need to correct anything because I multiplied by 10?

Here are a couple pictures.
