Question

Im a little fuzzy on the setup on this question: Find the center and radius of the given circle. x^2 + y^2 = 16

Answer 1

the center and radius of the given circle, \( x^2 + y^2 = r^2 \)
is C=(0,0) , radius =r.
can you find r ?

Answer 2

that would be 4^2 right? love your profile pic btw.

Answer 3

right, so r=radius =4 , center was (0,0)
and thanks :)

Answer 4

so is that it? that's all I need to do?
