I’ll make you the brainliest Part 1. What fractional part of the circle’s circumference is AB ? ( hint: A circle has 360 degrees ) (1 point)
———————————
Part 2: Use the fraction you determined in Part 1 and the circumference formula to find the length of AB. Show your work and round your answer to the nearest hundredth. (2 points)

Part 1: The fractional part of the circumference is 1/4.

Part 2: 100.53 or 100.48 if you use 3.14 as pi

Step-by-step explanation:

Part 1: A circle is 360 degrees and a right angle is 90, so the fractional  part is 90/360 or 1/4.

Part 2: 0.5pi*r is the length of the arc. The radius, or r, is 16 cm, a half of 32. It is 2 * pi * 16 = 32 * pi. 32 * pi = 100.53 or 100.48 if you use 3.14 as pi.
