Answer:
Standard Equation Of Circle is [tex](x-h)^2+(y-k)^2+r^2[/tex]
Step-by-step 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 ,
[tex](x-h)^2+(y-k)^2=r^2[/tex]
If center becomes origin then, Equation become
[tex]x^2+y^2=r^2[/tex]
