The equation of the circle whose radius is 3 units and whose center is the intersection of the lines x + 2y = 4 and x + y = 1. A. (x + 2)² + (y + 3)² = 9 B. (x – 2)2 + (y + 3)² = 9 C. (x – 2)² + (y – 3)? = 9 D. (x + 2)² + (y – 3)² = 9 I|

(x-18)2+(y+8)²=7 What is the radius of the circle?

2 Find the center and radius of the circle whose equation is x² + 5x + y? + 6y – 9 = 0. The center of the circle is The radius of the circle is
