Which of the following points represents the center of a circle whose equation is (x-3)^2 + (y-2)^2 =16
Question:
Answers
it’s (3,2)
Step-by-step explanation:
(3, 6)
Explanation:
Circle Function: (x - h)² + (y - k)² = r²
(h, k) of the function is the center, so (3, 6) is the center.
Alternatively, you can graph it and locate the center.
A. (3,2)
Step-by-step explanation:
To find the center of a circle on a quadratic equation all you have to do is to see what´s inside the parenthesis with the X and Y and then you equal that to "0", the number inside the parenthesis is the distance from the center of the circle to the center of the graph.
1. (x-3)= 0
2. x=3
1. (y-2)
2. Y=2
This means that the center of the circle is 3 units away on the positive x axis and the Y is 2 units away on the positive Y axis.
B
Step-by-step explanation:
(x-3)² + (y-2)² = 16
(x-h)²+(y-k)²=16
r=4
h=3
k=2
center is at the point (h, k) ⇒ (3, 2)

C
Step-by-step explanation:
The answer is whatever turns the two terms on the left to zero.
x - 3 = 0
x = 3
y - 6 = 0
y = 6
So the answer is (3,6)
which is C
compare with the equation of the circle (x-a)^2 + (y -b )^2 = r^2
(a,b) are the centers of the circle
therefore, the centers are (5,4)
Step-by-step explanation:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r the radius
(x - 5)² + (y - 4)² = 25 ← is in standard form
with centre = (5, 4) → D
The answer is option C
(3 , 6)
Hope this helps.
I think this is geometry. So you would have to use the standard equation of a circle.
The standard equation of a circle with center (h,k) and a radius of r is: (x-h)^2 + (y-k)^2 = r^2
With that equation, we know that the center of YOUR equation is (3 , 2).
So now make (x-3) and (y-2) equal to 0.
That would make x=3 and y=2.
Therefore the answer is A.
Your answer is A (3, 2)
