A circle is centered at (-3, 2) and has a radius of 2. Which of the following is the equation for this circle? (6 points)
O (x + 3)2 + (y - 2)2 = 2
O (x - 3)2 + (y + 2)2 = 4
O (x + 3)2 + (y - 2)2 = 4
O (x - 3)2 + (y + 2)2 = 2

Answer 1

(x + 3)² + (y -2)² = 4

Step-by-step explanation:

Circle Formula: (x -h)² + (y -k)² = r²

"r" is radius, "h" is x coordinates of center, "k" is y coordinate of center.

Here given:

• h = -3, k = 2, r = 2

Insert values:

(x -(-3))² + (y -2)² = 2²

(x + 3)² + (y -2)² = 4
