Question

Which is the equation of a circle with center (-2, 3) and radius r = 5?

Answer 1

Answer:

(x+2) ^2 + (y-3)^2 = 25  

Step-by-step explanation:

The equation of a circle is given by

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

(x--2) ^2 + (y-3)^2 = 5^2

(x+2) ^2 + (y-3)^2 = 25
