A circle has a diameter of 396 mm and an arc length of 88π mm.
396 π mm = circumference of the circle.
88 π mm = arc of 2/9 circumference
The angle measure of the arc is 80 degrees.

2 * pi * 396/2 = 396 * pi
88pi / (396 * pi) = T / 360
360 * 8 * 11 / (4 * 99) = T
360 * 2 / 9 = T
40 * 2 = T
80 = T
The angle is 80 degrees
