x2 + y2 = r2
x2 + y2 = R2
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.
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.
No. Every circle on the sphere whose center is also the center of the sphere is a great circle. If the circle's center is not also the center of the sphere, then the circle is a small circle.
The circumference of a circle represents its perimeter and the distance around it.
They must be congruent.
Since there are no equations following, the answer must be "none of them".
No it's made by the circle that how they get the circle not the center.
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.For a circle, the length of the diameter is the longest possible length of a chord.
