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 ="\\frac{\\theta} {360}2\\pi r"
="\\frac{45}{360}\u00d72\u00d73.142\u00d712"
=9.426cm
