IN WHAT IS A CIRCLE First of all we are to watch a round figure. In this figure a point revolves around a point. It remains at the same distance. This figure is known as a circle. So any figure in which a point revolves around another point such as it remains at the same distance from a fixed point it is called a CIRCLE .
Radius of the Circle-: The distance between the centre and the outer point at the circumference is known as the RADIUS of the circle.This remains the constant in the same circle.
Diameter of the circle-: The distance between two points situated at the circumference of the circle but passing through the center of the circle is known as the DIAMETER of the circle.
Area of the circle-: The space covered by the whole circle is known as the AREA of the circle. The formula to calculate area is as follow:Area of the circle =π R2
Circumference of the circle-: The round distance around the circle is known as the circumference of the circle. Circumference of the circle =2 π R Chord of the circle:Any line cutting the circle at two points inside the circle is known as the chord of the circle.
Half circle:The diameter of the circle divides the circle In two parts .Each part is called the HALF CIRCLE Tangent of the circle:Any line touching the circle at any one point is known as the TANGENT of the circle.
