Answer:

113.115 cm

Step-by-step explanation:

<u>Formula:</u>

C = 2πr

<u>Given:</u>

Radius: 22 cm

Diameter: 44 cm

The perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter.

Simply plug in your numbers to find the circumference first.

C = 2π(22)

C = 44π cm or 138.23 cm

Then, divide the circumference in half, and add your diameter.

Perimeter = (44π/2) + 44 = 113.115 cm
