Answer to Problem 28HP
Circumference formula can be used to measure the length of bracelet if it is not laid out straight.
Explanation of Solution
Given information:
There is a bracelet whose length is to calculated using the circumference formula.
Formula for circumference
This formula can be used if the bracelet is closed and represents a circle. In this case, measure the diameter and this formula can find the circumference.
Circumference in this case is the length of the bracelet.
However, opening the bracelet and laying it flat would not make it a circular object. Instead the new figure would resemble a straight line. This straight line can be simply measure using a rule or length measuring tape.
Circumference formula would only be used if the object becomes a circular object.
