Answer:
62.28
Explanation:
Ok, so since we know the radius of the circle and the area of the shaded region, we can find the fraction of the whole circle the shaded region is, and apply that to the total circumference to find the length of the arc.
1. area of whole circle = 17^2*3.14 = 907.46in^2
2. 529.35/907.46 = 0.5833314967
3. circumference of whole circle = 2*3.14*17 = 106.76
4. length of arc = 106.76*0.5833314967 = 62.2764705877 --> 62.28
