Consider circle H below. Part A: If XH = 10 feet and mxy = 100°, then determine the arc length of XY. Part B: If HY = 46 inches and myX = 75°, then determine the arc length of YX. Part C: If YX = 24 meters and mYX = 120°, then determine the radius of circle H. Part D: If XY = 78 miles and mxy = 70°, then determine the radius of circle H.
