Question

The circle below is centered at the point (4,3) and has a radius of length 5.

What is its equation?
A. (x-4)2 + (y + 3)2 =
52
B. (x-4)2 + (y - 3)2 = 52
C. (x-3)2 + (y - 3)2 =
52
D. (x+4)2 + (y-3)2 =
25

Answer 1

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

Explanation:

The equation for a circle is given by

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

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

We have a center of (4,3) and a radius of 5

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