Answer 1

Find the standard equation of the circle.

Answer 2

@sakigirl --> What are the coordinates of the center of the circle? Count on the diagram.

Answer 3

C: (2, 2)
r: 4

Answer 4

@sakigirl --> I think you counted on number 1 but I'm not sure. If so, I got (2,4) and r = 4. I was thrown off by each unit representing 2 and not the "usual" one.

Answer 5

I'm pretty sure the center's (2,2)

Answer 6

One number 2?

Answer 7

OH, gosh, I feel dumb. You're right, totally sorry about that.

Answer 8

I feel crazy because each block on number 1 is 2 units but on number 2, each block is 1 unit.

No, worries. Do you remember the standard form equation of a circle?

We are doing problem NUMBER two - right? :)

Answer 9

Yes. And isn't it (x-h)^2+(y-k)^2=r^2?

Answer 10

But for the center of the circle for number 2, I see (-3, 2)

Answer 11

Yes on the formula. On number 2--> C: (-3,2) and r: 2. Do you agree?

Answer 12

Yes.

Answer 13

You crank out the equation for number two. I'll do the same. Then, we'll compare answers.

Answer 14

(x+3)^3+(y-2)^2=4

Answer 15

( x - (-3) )^2 + (y - (2))^2 = 2^2
(x + 3) ^2 + ( y - 2) ^2 = 4

Answer 16

Oops, I meant to the squared of 2.

Answer 17

Your answer is correct. 2^2 = 4
