- Question:
Allison created an embroidery design of a stylized star emblem. The perimeter of the design is made by alternating semicircle and quarter-circle arcs. Each arc is formed from a circle with a 2 1/2 -inch diameter. There are 4 semicircle and 4 quarter-circle arcs, as shown in the diagram below.
To the nearest whole inch, what is the perimeter of Allison’s design?
