Question

Find the coordinates of the center and the length of the radius of the given circle.

(x)2 + (y)2 = 16

center at point =

radius =

Answer 1

\[(x-a)^{2}+(y-b)^{2}=r ^{2}\]
this is the standart equation of circle with center at (a,b) and radius r. Just compare it with the given equation

Answer 2

\[(x-0)^{2}+(y-0)^{2}=4^{2}\]

Answer 3

^that's the radius?

Answer 4

radious is 4

Answer 5

center is 0,0
