Ijust don’t know how to do it. i wasn’t in class to learn it.

Circumference of circle = πd = 24π in

Since inner arc PQ has an angle of 150°, 150° / 360° * 24π in = 10π in.

Step-by-step explanation:

The domain is the horizontal extent: all real numbers. -∞ < x < ∞.

The range is the vertical extent: all numbers greater than zero. 0 < y < ∞. (The graph never actually touches y=0, but comes arbitrarily close.)
