STEP - BY - STEP EXPLANATION

What to find?

The center and radius of each circle.

Given:

Step 1

State the general circle formula.


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

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

Step 2

Compare each equation to determine its center and radius.


A.(x-4)^2+(y+3)^2=16

The center is (4, -3) and radius = 3


B.(x-4)^2+(y-3)^2=16

The center is (4, 3) and radius is 4


C.(x+4)^2+(y+3)^2=16

The center is (-4, -3) and radius = 4


D.(x+4)^2+(y-3)^2=16

The center is ( -4, 3) and radius (r)=4

ANSWER

A. Center (4, -3) and r=4

B. Center (4, 3) and r=4

C. Center (-4, -3) and r=4

D. Center (-4, 3) and r=4
