Question

2. Which of the following is the equation of a circle with the radius of 1.5 and its center at (-3,2)?

A. (x+3)^2+(y-2)^2=1.5
B. (x-3)^2+(y+2)^2=1.5
C. (x+3)^2+(y-2)^2=2.25
D. (x-3)^2+(y+2)^2=2.25

Answer 1

(x - xo)^2 + (y - yo)^2 = r^2

[x - (-3)]^2 + [y - (2)]^2 = (1.5)^2

(x+3)^2 + (y-2)^2 = 2.25

Answer: option C
