Pi ( Â ):Â An approximate value of Â is 22/7 which is correct to two decimal places. A more accurate value of Â is 3.14159 which is correct to five decimal places. Â
Radius: The constant distance of every point on the circle from its centre is called the radius of the circle. It is half of the diameter.
Sector:Â A sector is that part of a circle, which lies between an arc and two radii joining the extremities of the centre. The most important sector is a quadrant, which is one-fourth of the circle. Â
Tangent of a circle:Â It is a line perpendicular to the radius that touches only one point on the circle.
Circumference of a circle: = 2 r where Â is 22/7 or 3.14159
