Write an equation of the circle with center (9, - 3) and radius 8.

(x-9) ^2 + (y+3) ^2 = 8^2

or

(x-9) ^2 + (y+3) ^2 = 64

Step-by-step explanation:

An equation for a circle can be written as

(x-h) ^2 + (y-k) ^2 = r^2 where (h, k) is the center and r is the radius

(x-9) ^2 + (y - - 3) ^2 = 8^2

(x-9) ^2 + (y+3) ^2 = 8^2

or

(x-9) ^2 + (y+3) ^2 = 64
