Question

Instructions: Given the equation of the circle, find the center and radius

Answer 1

Center: (1,2)
Radius: 4

Answer 2

The center is (1,2) and the radius is 4

Explanation:

The equation of a circle is given by

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

where ( h,k) is the center and r is the radius

(x-1)^2 + (y-2)^2 = 4^2

The center is (1,2) and the radius is 4
