How to find the measure of the intercepted arc?I have to find the measure of an intercepted arc in a circle of radius 10 cm with the given radian...

The circumference of a circle is given by 2*pi*r where r
is the radius of the circle. Here the radius is 10 which gives the circumference as
20*pi.

Angles can be expressed in many units, one of which
is radians. One radian is the measure of an angle such that the length of the
intercepted arc is equal to the radius of the circle. This makes the length of the arc
intercepted by an angle of 2*pi radians equal to the circumference of the
circle.

To find the measure of the intercepted arc; when
the angle is A radians, the measure of the intercepted arc is
A*r.
