Answer:
26.85 in
Explanation:
The circumference of the whole circle of diameter 5 in is C = πd, which here is C = π(5 in), or approximately 5π in. We take only half of this, since the figure shows a semicircle, not a full circle. Then the half-circumference is (5/2)π.
To find the perimeter: add up the lengths forming the perimeter:
7 in + (5/2)π in + 7 in + 5 in, or:
19 in + (5/2)π ≈ 26.85 in
