Question

Write an equation for a circle with center at (5,-2) and diameter of 8 centimeters.

I’ll give Brainlessly or whatever it’s called

Answer 1

`(x-5)^2+(y+2)^2=16`

Explanation:

lol brainlessly...

General Circle function:
`(x-h)^2+(y-k)^2=r^2`, where h is the x-coordinate of the center, k is the y-coordinate of the center, and r is the radius.

The radius of the circle is half the diameter so: 8 / 2 = 4

The x-coordinate of the circle is 5

The y-coordinate of the circle is -2

Plug in.

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

`(x-5)^2+(y+2)^2=16`
