Question

Write an equation of the circle with center (-3, 5) and radius 4.

Answer 1

Answer:

(x+3)^2 + (y-5)^2 = 4^2

or

(x+3)^2 + (y-5)^2 = 16

Step-by-step explanation:

The equation of a circle can be written in the form

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x--3)^2 + (y-5)^2 = 4^2

(x+3)^2 + (y-5)^2 = 4^2

or

(x+3)^2 + (y-5)^2 = 16
