The standard equation of a circle, given the radius r units and center (h,k) is given by:

From the question, we have the center of the circle to be (3,1) and the radius is 2 units.
We substitute the center and radius of the circle into the equation to get:

The correct answer is C
Answer:
arc length = radius * central angle in degrees * (PI / 180)
arc length = 7 * 90 * (3.14159265 / 180)
arc length = 10.995574275
