You present facts, but I don't see a QUESTION in your illustration.  What is your goal?

@mathmale two questions down at the bottom:  find the length of arc ACB, find the area of the shaded region

whpalmer4 · Answer

2 pi radians = 360 degrees.  you know the radius is 15 cm, so you can find the circumference of the circle.  to find the arc length of ACB, just take the proportion that 2 radians is of 2 pi radians and multiply by the circumference.

A similar approach will get you the shaded area: find the area of the entire circle, then multiply by the fraction of 2 pi radians that is occupied by the shaded region
