Answer:
arc length = 2 * pi * r * (0.725)
Step-by-step explanation:
arc length = 2 * pi * r * (c/360)
arc length = 2 * pi * r * ( (360 - 99) / 360)
Arc AXB is 261 degrees
A circle has 360 degrees, so arc AB + arc AXB have to be equal to 360 degrees. Arc AB is 99 degrees, as shown, so we substitute 99 degrees for AB. 99 + arc AXB = 360 which gives us arc AXB = 261 when we simplify.
