Question

The circle with center o has a circumference of 8pi inches. The central angle is 60 degrees. What is the length of the minor arc BSA

Answer 1

4 pi/3 inches

Explanation:

The sum of angles at a point is 360

It is expected that the total angle at the center of the circle is 360

Now, we have it that the arc subtends an angle of 60 degrees at the center of the circle

what this mean is that the arc is 1/6 of the circle since 360/60 is 6

So by finding one-sixth of the circumference of the circle, we can get the length of the arc

So we have this as 8 pi/6 = 4pi/3 inches
