Center: $(\frac{1}{2},\frac{1}{2})$; Radius: $r=\frac{3}{2}$

Work Step by Step

Equation of a circle: $(x-h)^2+(y-k)^2=r^2~~ $ (standard form) Center: $(h,k)$; Radius: $r$ $(x-\frac{1}{2})^2+(y-\frac{1}{2})^2=\frac{9}{4}$ $(x-\frac{1}{2})^2+(y-\frac{1}{2})^2=(\frac{3}{2})^2$ $h=\frac{1}{2}$, $k=\frac{1}{2}$, $r=\frac{3}{2}$
