Question

What is the equation of the following graph?

Answer 1

The graph represents the circle with centre (h,k)=((0,0) and radius, r= 10 units.

And the equation of circle is

`(x-h)^2 +(y-k)^2 = r^2`

Substituting the values of h,k, and r, we will get

`(x-0)^2 +(y-0)^2 = 10^2`

`x^2 + y^2 = 100`

And that's the required equation of the graph .
