Question

Arc cd is of the circumference of a circle. what is the radian measure of the central angle?

Answer 1

We know that one degree of a circle is equivalent to pi over 180 (π/180)

¼ of a circle is equivalent to 90 degrees of a circle

And when we look at 180 degrees over 90 degrees it will give us 2

So the answer for this would be pi over 2 or you can also write this as pi/2

So the answer for this question is π/2

Answer 2

Answer:

B. π/2 radians
