Yeah, your right. I figured it out. We did a test with the 25 inch bag, and tried to get a circumference from it. It’s about 2/3 of the width. But just messing with the calculator, I figured that since we’re dealing with circles it would make much more sense that the “about 2/3” would actually be pi. So, take the width, divide by pi, times that by two, times that by pi and you get the circumference of double the original width. Which seems so simple now. I’ll claim a brain fart as my excuse.
I think I approached this problem from the wrong side and came up with the answer in a round about way rather then with straight forward thinking.
Thanks for the reply, good to know that the round about way I came up with it works.
