Question

Can someone help me answer this please

Answer 1

the radius of the circle is 3

the center point is (4,2)

Answer 2

The center is at (4,2) and the radius is at 3

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-4)^2 +(y-2)^2 = 9

(x-4)^2 +(y-2)^2 = 3^2

The center is at (4,2) and the radius is at 3
