Find the equation of the circle with n (1,3) as the center and tangent to the line 3x-4y-7 = 0

Find the equation of the circle with n (1,3) as the center and tangent to the line 3x-4y-7 = 0

Because the distance between the point n (1,3) and the straight line 3x-4y-7 = 0 is d = | 3-4 × 3-7 | 5 = 165, and the radius of the circle is r = D = 165, then the equation of the circle is: (x-1) 2 + (Y-3) 2 = 25625
