Circle P has a radius of 8 units with center P at (2, -1). Which equation defines circle P? (x + 2)2 + (y – 1)2 = 64

(x – 2)2 + (y + 1)2 = 64

(x – 2)2 + (y + 1)2 = 8

(x + 2)2 + (y – 1)2 = 8

Can anyone help? Please i'd truly appreciate it

anonymous · Answer

(x – 2)^2 + (y + 1)^2 = 64 . Plug in the values into the equation of the circle.

anonymous · Answer

yeah sorry i'm solving it. I didn't notice you responded lol

anonymous · Answer

Doesn't seem like that's the answer.....

anonymous · Answer

Would it be the last one?

anonymous · Answer

Nope, It is definitely (x – 2)^2 + (y + 1)^2 = 64

equation of a circle is
(x - a)^2 + (y - b)^2 = r^2

where center is (a,b)  and radius = r
