中心 (x-1/2)^2+(y-1/2)^2= 9/4

解

中心

(x - \frac{1}{2})^{2} + (y - \frac{1}{2})^{2} = \frac{9}{4}

(\frac{1}{2}, \frac{1}{2})

解答ステップ

(x - \frac{1}{2})^{2} + (y - \frac{1}{2})^{2} = \frac{9}{4}

(x - \frac{1}{2})^{2} + (y - \frac{1}{2})^{2} = \frac{9}{4}

を標準的な円のequationの形式で書き換える

(x - \frac{1}{2})^{2} + (y - \frac{1}{2})^{2} = (\frac{3}{2})^{2}

ゆえに円の特性は:

(a, b) = (\frac{1}{2}, \frac{1}{2}), r = \frac{3}{2}

中心は:

(\frac{1}{2}, \frac{1}{2})
