A circle is defined by the equation x2 + y2 - x - 2y - = 0. What are the coordinates for the center of the circle and the length of the radius?

x² + y² - x - 2y = 0

x² - x + y² - 2y = 0

x² - x + 0.25 + y - 2y + 4 = 0 + 0.25 + 4

(x - 0.5) ² + (y - 2) ² = 4.25

Center: (0.5, 2)

Radius: 2.061552813

The center is equal to (0.5, 2) and the radius is equal to 2.061552813.
