Answer:

πr + 2r

Step-by-step explanation:

Perimeter of Semicircle

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.

Step-by-step explanation:

1. d = 22mm

circumference = πr + d

= 22/7 × 11 + 22

= 56.57 mm

2. r = 4 inches

circumference = πr + d

= 22/7 × 4 + 8

= 20.57 Inches

3. d = 10 yards

circumference = πr+d

= 22/7 × 5 + 10

  • = 25.71 yards
