Question

Write the equation of the circle with center (7,-2) and radius square root 61. Please show your work!

Answer 1

The equation of a circle is (x - h)^2 + (y - k)^2 = r^2
x and y are left alone in a circle equation, while h and k are the coordinates of the center.

Thus, our equation is (x - 7)^2 + (y + 2)^2 = 61
