Answer 2

You can use this:
\[(x-a)^2+(y-b)^2=r^2\]
r is the radius:
(a, b)=center

Answer 3

0,1?

Answer 4

is the center i mean

Answer 5

That's right!

Answer 6

And what about the radius?

Answer 7

2

Answer 8

Excellent! So the equation is?

Answer 9

x2 + (y – 1)2 = 2

Answer 10

?

Answer 11

LHS is right..

Answer 12

so i'm right?..

Answer 13

r = 2..

So according to the equation \(r^2\) = ???

Answer 14

x^2+(y-1)^2=2^2

Answer 15

RHS is not right..

Answer 16

x2 + (y – 1)2 = 4?

Answer 17

\[x^2+(y-1)^2=4\]

Answer 18

Yes you are right now..

Answer 19

Well done!
