Well actually the measure of ARC YZ depends on the radius of the circle (supposing Y and Z are points on the circumference and O is the center of the circle)
So if the measure of the angle YOZ is 68° then considering that the measure of the entire circumference is 2rPi where r is the radius of the circle, and the fact that the circumference is the arc of 360° then the measure of the arc YZ is
2rPi * 68/360 = 17rPi/45

If Y and Z are on the circumference of the circle and O is at the center of the circle, then the measure of the central angle equals the measure of the subtended arc.

In other words, m Arc YZ = m
Arc length is given by technique of s = r?, the place ? is in radians. a hundred and eighty° = ? radians a million° = ? / a hundred and eighty radians a hundred and twenty°(? / a hundred and eighty°) = 120? / a hundred and eighty = 2? / 3 radians s = 8(2? / 3) s = 16? / 3 ? sixteen.8 inches
