Question

Write an equation of the circle with center (8.-3) and radius 2

Answer 1

Answer:
`(x-8)^2+(y+3)^2=4`

Explanation:

The equation of a circle is
`(x-h)^2+(y-k)^2=r^2`. h and k are the points of the center corresponding with x and y respectively. r is radius. All we have to do is plug the values in.

`(x-8)^2+(y-(-3))^2=2^2`

With our values plugged in, we can now simplify.

`(x-8)^2+(y+3)^2=4`

Therefore, our final equation is
`(x-8)^2+(y+3)^2=4`.
