What is Meant by Circle?
In Mathematics, the circle is defined as a two-dimensional closed figure where all points on the surface of the circle are equidistant from the centre point. The distance between the centre and the surface of the circle is called the radius. The diameter is the straight line that passes from one side of the circle to the other side through the center. The diameter is double the radius. The area and the circumference of the circle is given by the formula,
Area of the circle, A = πr2 Square units
Circumference/perimeter of the circle= 2πr units
