A circle has a radius of 12.6 cm. What is the exact length of an arc formed by a central angle measuring 100°?
Total circumference = pi * d = pi ( 2 * 12.6) = 25.2 pi cm
this arc is a fraction of the 360 degree circumference 100 / 360
100/360 * 25.2 pi = ........... cm
Total circumference = pi * d = pi ( 2 * 12.6) = 25.2 pi cm
this arc is a fraction of the 360 degree circumference 100 / 360
