Question

Write the equation of the circle with a center (5, -7) and radius = 7

Answer 1

`(x-5)^(2) + (y+7)^(2) = 49`

Explanation:

Answer 2

9514 1404 393

Answer:

(x -5)^2 +(y +7)^2 = 49

Explanation:

The equation of the circle with center (h, k) and radius r is ...

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

Putting (h, k) = (5, -7) and r = 7 into this form, your equation is ...

(x -5)^2 +(y +7)^2 = 49
