Question

A circle has the equation (x−13)2+(y−1)2=4. A: What is the center of the circle? B: What is the radius of the circle?

Answer 1

The center is (13,1) and the radius is 2

Explanation:

The equation of a circle can be written as

(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x-13) ^2 + (y-1)^2 = 2^2

The center is (13,1) and the radius is 2
