Find the equation of a circle satisfying the given conditions.
-Center: $(1,0)$; radius: 2
A) $x^{2}+(y-1)^{2}=2$
B) $(x-1)^{2}+y^{2}=4$
C) $(x+1)^{2}+y^{2}=4$
D) $x^{2}+(y+1)^{2}=2$

Question

Quizplus · Accepted Answer

The general equation of a circle is $(x-h)^{2}+(y-k)^{2}=r^{2}$, where $(h,k)$ is the center and $r$ is the radius. For a circle with center $(1,0)$ and radius $2$, the equation is $(x-1)^{2}+y^{2}=4$.
