Answer:

Perimeter= 57.12

Step-by-step explanation:

To find circumference, the equation is 2 x 3.14 x r

When you plug in the numbers, you get 50.24. Since it's a half circle, you divide that number to get 25.12. Then, you add the two side side lengths of the triangle, 16+16, to get 32. (Don't add the the last side of the triangle because it's not part of the perimeter)

When you add 25.12 to 32, you get 57.12.
