Question 261768
I'm assuming that the bracelet forms a circle. If you were to cut the bracelet at one point and lay it out as long as you can (without breaking it further), then the bracelet would be 7.9 inches long. Since the circumference is simply the distance out the circle, this means that the circumference is 7.9 inches. You can use the circumference formula {{{C=pi*d}}} where {{{pi=3.14}}} (approximately) and 'd' is the diameter. So just plug in {{{C=7.9}}} and {{{pi=3.14}}} to get {{{7.9=3.14d}}}. Now just solve for 'd' in the equation {{{7.9=3.14d}}} to find the diameter.
