Question

Find the equation of the circle whose center and radius are given.

center ( -2, -5), radius = 1

Answer 1

Given \(\large\rm center=(\color{orangered}{h},\color{royalblue}{k})\) and \(\large\rm radius=\color{green}{r}\)

Then our standard form is: \(\large\rm (x-\color{orangered}{h})^2+(y-\color{royalblue}{k})^2=\color{green}{r}^2\)
