Question

A circle is centered at (−3, 2) and has a radius of 2. Which of the following is the equation for this circle?
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 1

in your case (x, y)=(-3, 2)

Answer 2

substitute your input and get your eqaution

Answer 3

So, is the answer D?

Answer 4

no

Answer 5

your point is (-3, 2)

thus (x-(-3))^2+(y-2)^2=...

Answer 6

no as well

-(-)=3

thus we have (x-(-3))^2+(y-2)^2=... =>(x+3)^2.......

Answer 7

woops

Answer 8

-(-)=+ i meant

Answer 9

A?

Answer 10

nearly:

left part is correct, but the right one is incorrect: because the right sides = r^2, not r
