Q:
# which graph represents a circle with equation x2 + y2 = 9

Accepted Solution

A:

The basic form of the equation of a circle is:

x^2+y^2=r^2

where r^2 is the radius squared.

Looking at your equation, x^2+y^2=9, the radius is 3 (sqrt of 9 is 3)

Therefore, the graph B would be correct since the radius of the circle at all points is 3.

Hope I helped :)
