Answer:
28.56 inches
Explanation:
you need to find the circumference of a circle with a diameter of 4, ∴ radius is 2
C = 2πr
C = 4(3.14)
C = 12.56
Now add 12.56 to the two sides that are 6 inches and also add the four 1 inch segments to the right and left of each semi-circle.
12.56 + 2(6) + 1(4) = 12.56 + 12 + 4 which totals 28.56
