Mark me as brainliest

Step-by-step explanation:

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

Answer 2

Answer:

perimeter of semicircle = r(22/7+2)

s = r = 7.51

7.15 (22/7+2)

38.62
