Answer:

( x + 3)² + ( y + 7)² = 361

Explanation:

The equation of a circle written in standard form is ( x – h)² + ( y - k)² = r². The center is (h, k) and the radius is r.

With the given information of center (-3, -7) and radius 19, we get

[ x – (-3)]² + [ y - (-3)]² = (19)²

( x + 3)² + ( y + 7)² = 361
