What is the center and radius of the circle with the equation (x - 2)2 + (y - 7)2 = 49

The equation of a circle:

(h, k) - coordinates of a center

r - a radius

We have:

The center: (2, 7)

The radius: r² = 49 → r = √49 → r = 7

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
