Question

How do you write an equation in standard form of the circle with the given properties: radius: 5 and center: (0,0)?

Answer 1

I found: `x^2+y^2=25`

Explanation:

I would use the general relationship:
`(x-h)^2+(y-k)^2=r^2`
with:
`h,k` are the coordinated of the center, `(0,0)` in this case;
`r=5` is the radius.
Getting:
`x^2+y^2=25`
