.
OAB is a sector of a circle, center O, radius 8 cm.
Angle AOB=56º.
M is the midpoint of the chord AB.
OM is perpendicular to the chord AB.
CALCULATE
A) the length of the arc AB
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

the length of the arc AB = 2%2Api%2A8%2A%2856%2F360%29.

Please complete calculation yourself.

The rest of the condition is irrelevant to this problem.
