Question

[7.02] Identify the center and the radius of the circle with equation (x - 6)2 + y2 = 49.

Answer 1

The general equation of a circle is:

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

The equation above fits this form as follows:

(x - 6)^2 + (y - 0)^2 = 7^2

Therefore:

Center (h,k) = (6,0)
Radius = 7

Answer 2

Thank You so much!
