Question

3. write an equation of the circle whose center is (-5,2) and whose radius length is 4 express your answer in standard form. I NEED MY WORK TO BE SHOWN PLEASE HURRY I AM BEING TIMED!!!!!

Answer 1

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

Center is (h,k) h = -5, k = 2
Radius is 4, r = 4

(x - -5)^2 + (y - 2)^2 = 4^2
(x + 5)^2 + (y - 2)^2 = 16
