Answer:
the answer would be D, .A circle is the set of all points in a plane that are the same distance from a fixed point called the center.
The definition of a circle is " A circle is the set of all points in a plane that are the same distance from a fixed point called the center" so option (4) will be correct.
A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
In our daily life, we always see circle objects for example our bike wheel.
The longest line which can be drawn inside the circle will be the diameter.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
A circle is a round plan figure but to draw the circle we need to draw a locus of an infinite point that has the same distance from a fixed point called the center.
Hence, a circle is the set of all points in a plane that are the same distance from a fixed point called the center will be correct.
