Question

If the center of a circle is at

(5,-3) and its radius is 4, complete
its equation:
(x – [? ])2+(y - [ ])2= []

Answer 1

(x - 5)² + (y + 3)² = 16

Explanation:

(x - h)² + (y - k)² = r²

(h, k) is the center = (5, -3)

r is the radius = 4

r² = 4² = 16

Answer 2

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