x2 + y2 = r2
Since there are no equations following, the answer must be "none of them".
The center point is (5,4)
x2 + y2 = R2
This starts with the collocation circle to go through the three points on the curve. First write the equation of a circle. Then write three equations that force the collocation circle to go through the three points on the curve. Last, solve the equations for a, b, and r.
No it's made by the circle that how they get the circle not the center.

In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
x2 + y2 = R2
This is referred to as a chord. If the chord passes through the center of the circle, it represents the diameteror width of the circle.
x2 + y2 = 25radius of 10?x2 + y2 = 100

It's important to know the formulas for all these characteristics of circles, and to recognize what they have in common. Area of a circle = πr2 Circumference of a circle = 2πr or dπ Where in the above equations r represents radius, and d is diameter (2r). Both these equations have r in them. Find the radius using the circumference equation, and then plug it into the equation for Area
