Find the center of the circle if the endpoints of a diameter of the circle are at (-9, -4) and (2, 9).

The point (-3, 4) is on a circle with center (1, -1). Write the standard equation of the circle.

• (x + 1)² + (y - 1)² = 41

• (x - 1)² + (y + 1)² = 16

• (x + 1)² + (y - 1)² = 1681

• (x - 1)² + (y + 1)² = 41

What is the radius of the circle?
