Formulate at least two problems invovlimg arcs and central angles,thensolve
1.Find m∠CAE
The degree measure of a minor arc is equal to the measure of the central angle that intercepts it. Therefore,
m∠CAE=140°
2.Calculate the arc length of a sector whose central angle is 45° and the radius of 12 cm.
Arc Length =
=
=9.426cm
