First, you have to find the arc length of the sector. To do that, use the formula for arc length.

Since the figure is a semicircle, we know the central angle is 180, so plug that in for x. We also know the diameter, which is 5. So plug that in for d. Once you get the arc length, add 5 to it. 5 is the diameter and is part of the perimeter
The equation should be X=2
