Determine the center and radius of the following circle equation:

x2 + y2 + 6x + 187 – 10 = 0

Center:
Radius:

answer: 2530

hope this

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
