Question
In Exercises $13-20,$ write the equation of the circle in standard form. Then identify its center and radius. $$\frac{9}{2} x^{2}+\frac{9}{2} y^{2}=1$$
Step 1
The standard form of a circle's equation is $(x-h)^2 + (y-k)^2 = r^2$, where $(h,k)$ is the center of the circle and $r$ is the radius. The given equation is $\frac{9}{2}x^2 + \frac{9}{2}y^2 = 1$. Show more…
