Question

What is the equation of a circle with a center (-9,2) and radius 5?

Answer 1

(x+9)^2 + ( y-2) ^2 = 25

Explanation:

The equation of 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-2) ^2 = 5^2

(x+9)^2 + ( y-2) ^2 = 25
