Question

I have two circles. One has a radius of 2 and the other, 4. How can I find area and figure out their equations? BTW, the center for both is at (6,4)

Answer 1

area = \(\pi r^2\)

Answer 2

Hello, Facepalm.:)
:P

Answer 3

what's the problem?

Answer 4

Thanks! :D I need to know the formula for finding the equation of the circles. Their center at (6,4).

Answer 5

oh lol...you should memorize those formulas...they are very common in later maths

Answer 6

Yeah. :|

Answer 7

I meant the equation of the circle itself. :S

It's like, (x + 5)(y + 5) = r or something.

Answer 8

oh lol \( (x-h)^2 + (y - k)^2 = r^2\) were (h,k) = center

Answer 9

that's the distance formula actually :p

Answer 10

see?

Answer 11

just some additional info...not really essential

Answer 12

OH! Thank you! :DDDDD
