**This space is for those who are ***fascinated by MATHS* ,try their hands on it but end up getting confused because of non-clarity of concepts.

The chapter i am going to start with is CIRCUMFERENCE AND AREA OF CIRCLES.....**Prerequisite knowledge : Take a fixed point on the plane and mark it as O . Take a fixed distance mark it as 'R' . Keeping the end at O fixed and moving the other end of 'R' , the figure thus obtained is a circle .****All the points of this figure are at equal distance from O .(all the points in colour blue)****O-is called the centre of the circle .****R-is the radius of the circle .****Circles around us: Bangle , Rim of a cellotape .****Rim of a wheel.****Circumference (or perimeter) of the circle:is the measure of the boundary of the circle.****Lets do an activity to find circumference of certain circular figures....****Bangle:mark a point at the boundary of the bangle . Take a thread and start wrapping it around the boundary starting from the marked point . Continue till you reach the marked point again , cut out the wrapped up piece of thread .**

**Measure this length of the thread using a ruler.**

**This length of the thread wich measures the boundary of the bangle is the circumference of the given bangle.**
