Question

How do you find the center and radius of the circle given `(x-4)^2+y^2=16/25`?

Answer 1

Center is at `(4,0)`.
Radius is `4/5`.

Explanation:

The formula for a circle is:
`(x – h)^2 + (y – k)^2 = r^2`
where `(h,k)` is the center, and `r` is the radius.

`(x-4)^2+(y-0)^2=(4/5)^2`

`(4,0)` is the center.
`4/5` is the radius
