Question

Find the equation of the circle with:

Centre (a, b) and radius √a² + b²

Answer 1

Given that we need to find the equation of the circle with centre (a, b) and radius \(\sqrt{a^2 + b^2}\)

We know that the equation of the circle with centre (p, q) and radius ‘r’ is given by: 

⇒ (x - p)² + (y - q)² = r² 

Now we substitute the corresponding values in the equation:
