Question

What is the measure of DF? Or how do I find it exactly?

Answer 1

Is the measurement of the central angle the same as the arc?

Answer 2

Yes.

Answer 3

An arc has the same degree measure as the central angle that intercepts it.

Answer 4

Since a whole circle equals 360 degrees, you would have to do 360-60=300.
Arc DF would be 300 degrees.

Answer 5

But DF is within the two lines...?

Answer 6

It's asking about the minor arc.

Answer 7

The major arc would be 300.

Answer 8

the arc is given by the formula:
\[s=r \theta\] where s is the arc length, r is the radius and \[\theta\] is the angle in radian

Answer 9

It's 60 degrees. Thank you for the help.

Answer 10

The minor arc would be 60 degrees and the major arc would be 300 degrees.
