Question

What is the equation of the given circle?

Answer 1

A.) (x-3)^2+(y+2)^2=2
B.) (x+3)^2+(y-2)^2=2
C.) (x-3)^2+(y+2)^2=1
D.) (x+3)^2+(y-2)^2=1

Answer 2

can you identify the radius and center of the circle?

Answer 3

center (-3,2)

Answer 4

radius = 1?

Answer 5

If you know the circle has radius \(r\) and a center at \((h,k)\), the equation will be
\[(x-h)^2+(y-k)^2=r^2\]

Answer 6

let's assume you are correct about the radius, what would the equation be? Then we'll test a point and see if you are right!

Answer 7

equation would be (x-9)+(y+4)=1

Answer 8

or B

Answer 9

i simplified it too much lol

Answer 10

well, no. for one thing, yeah, your "simplification" is "interesting" :-)

Answer 11

Let's do the radius first. you thought the radius was 1, right? if \(r = 1\), what is \(r^2\)?
