Answer:
<h2><em><u>
15.71 is the perimeter.</u></em></h2>
Step-by-step explanation:
Perimeter = Circumference
<em><u>Step 1. Know and recognize what you have</u></em>
C = pi*d
pi = 3.142
d = 10
<em><u>Step 2. Solve for the circumference of whole circle</u></em>
C = 3.142*10
C = 31.42
<em><u>Step 3. Solve for the questions answer</u></em>
C of semicircle = 31.42/2
<h2><em><u>
C of semicircle = 15.71</u></em></h2><h2><em><u>
</u></em></h2>
