Find the equation of the circle with: centre `(a , b)` and radius `sqrt(a^2+b^2)dot`

Explanation

We equation of circle with radius` \gamma` and centre `(x_{0}, y_{0}) is (x-x_{0})^{2}+(y-y_{0})^{2}=\gamma^{2}`


here centre is `(a, b),` radius` =\sqrt{a^{2}+b^{2}}`




So equation is `(x-a)^{2}+(y-b)^{2}=a^{2}+b^{2}`
