Question

What is the measure of the arc ?

Answer 1

Answer:

Recall that a portion of a circle is called an arc. One way to measure an arc is with degrees. The measure of an arc is equal to the measure of its corresponding central angle. Below, m^DC=70∘and m^GH=70∘. ... Previously, you have measured all angles in degrees, but you can also measure angles in radians.

Answer 2

The circumference of the circle is also the arc of circle.

So, the measure of the arc is 360°.
