A circle is centered at (−3, 2) and has a radius of 2. Which of the following is the equation for this circle?a.
a. (x + 3)2 + (y − 2)2 = 2
b. (x − 3)2 + (y + 2)2 = 4
c. (x + 3)2 + (y − 2)2 = 4
d. (x − 3)2 + (y + 2)2 = 2

Answer:

c. (x + 3)² + (y - 2)² = 4

Step-by-step explanation:

The general equation of a circle:

(x - a)² + (y - b)² = r² where (a, b) is the centre = (-3, 2) and r = radius = 2.

(x - (-3))² + (y - 2)= 2²

(x + 3)² + (y - 2)² = 4
