Question

What is the standard equation of the circle in the graph?

Answer 1

x^2 + y^2 = radius^2
Is that what your adking for? This is for a circle around the origin.

Answer 2

Standard Equation Of Circle is
`(x-h)^2+(y-k)^2+r^2`

Explanation:

Let we are given a circle in graph with center P whose coordinate are ( h , k ) and radius of the circle is r units.

Then the standard equation of circle is written as ,

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

If center becomes origin then, Equation become

`x^2+y^2=r^2`
