Answer:

Step-by-step explanation:

PX is 15 which is the radius

Find the circumference of the circle and subtract the length of the minor arc

Circumference of circle = 2 * pi * r = 2 * pi * 15 = 30 pi

length of arc = angle/360 * 2 * pi * r = 23/360 * 2 * pi * 15 = 1.92 pi

subtraction will give 30 pi - 1.92 pi = 28.08 pi

28.08 * 22/7 = 88.25 which is approximately 88
