Which equation represents the circle described? The radius is 2 units. The center is the same as the center of a circle whose equation is x squared plus y squared minus 8 x minus 6 y plus 24 is equal to 0

Complete the square in x² + y² − 8x − 6y + 24 = 0: (x − 4)² + (y − 3)² = 1, so the center is (4, 3). A circle with that center and radius 2 has equation (x − 4)² + (y − 3)² = 2². Therefore, choice B is correct; the right side must be the radius squared, 4.
