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)

Question

lgbasallote · Answer

area = $\pi r^2$

Hello, Facepalm.:)
 :P

lgbasallote · Answer

what's the problem?

anonymous · Answer

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

lgbasallote · Answer

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

anonymous · Answer

Yeah. :|

anonymous · Answer

I meant the equation of the circle itself. :S 

It's like, (x + 5)(y + 5) = r or something.

lgbasallote · Answer

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

lgbasallote · Answer

that's the distance formula actually :p
