Answer:

The equation that represents the circle is (x-14)^{2} + (y-9)^{2} = 13

Step-by-step explanation:

Given the center of circle (14,9) passes through point (16,12)

We know that the equation of circle is

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

where (x,y) is any point on the circle, (h,k) is center of the circle and r is radius of circle.

From given data (x,y) is (16,12) and (h,k) is (14,9). Substituting these values in equation of circle, we get

(16-14)^{2} + (12-9)^{2} = r^{2}

r^{2} = 2^{2} + 3^{2}

r^{2} = 13

Substituting the values of (h,K) and  r^{2} as (14,9) and 13 respectively in equation of circle, we get

(x-14)^{2} + (y-9)^{2} = 13

Hence the equation that represents the circle is (x-14)^{2} + (y-9)^{2} = 13
