Look at the circle shown below.
What is the equation of the circle?
Answer

x2 + (y – 2)2 = 36

x2 + (y – 2)2 = 6

(x – 2)2 + y 2 = 36

(x – 2)2 + y 2 = 6

what's its radius?

anonymous · Answer

6 without being squared but im not sure if it wants me to square it or not

parthkohli · Answer

$\Large \color{MidnightBlue}{\Rightarrow (x - h)^2 + (y - b)^2 = r^2 }$

Radius i.e 6 can be squared to form 36. So it'll be 36 :D

Thank you again @lalaly :P

lol dont thank me :D

anonymous · Answer

thank-you guys =)

anonymous · Answer

how do i find the equation though?

anonymous · Answer

You have the graph.  count how many x ticks the centre is over, count how many y ticks your centre is over.  Those are your h and b values in the equation that @Parthkohli gave.  sub them in and you have your equation

mmmk thanks
