Answer:
The perimeter of a semicircle includes the arc and the diameter. Here are some formulas that you can use.
Step-by-step explanation:
P = C / 2 + d
where C is the circumference of the whole circle
P = π r + 2r
where r is the radius
P = (2 + π) r
P = (d π / 2) + d
P = d π / 2 + 2 d / 2
P = (d π + 2 d) / 2
P = (2 + π) d / 2
