Question

The circle below is centered at the point (3,1) and has a radius length of 2.What is its equation

Answer 1

Answer:

C. $(x-3)^2+(y-1)^2=2^2$

Step-by-step explanation:

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

$(x-h)^2+(y-k)^2=r^2$

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:

$(x-3)^2+(y-1)^2=2^2$

The correct answer is C
