The perimeter of a circle is finding the circumference of the circle
--> calculated by the equation:
![\pi D = 2\pi R](https://img.qammunity.org/2023/formulas/mathematics/high-school/ltbycphzmcb53uo3shjl9epkenjhfn2jhe.png)
A semicircle has half of the circumference of the circle, thus the circumference equation is
-->
![(1)/(2) \pi D = (1)/(2) *2*\pi *r](https://img.qammunity.org/2023/formulas/mathematics/high-school/5cexrk488eml9yjo337bwtchp7xwn98r4q.png)
We are given:
- Diameter --> 17 in
= 3.14
Now let's calculate
![(1)/(2) *3.14*17 = 26.69 in^2](https://img.qammunity.org/2023/formulas/mathematics/high-school/z0qzdzxhprmogtkds1uv8tia6pfxco4gnc.png)
Hope it helps!
