Question

Objective:
To find the ratio of circumference and diameter of a circle.
Procedure:•Cut a circle of radius 5 cm.•Fold it into two halves to obtain a line of folding AB.
Draw a ray on a paper and mark its initial point as P.

Demonstration:•Hold the circular disc such that point B on the circle coincides with point P on the ray.•. Rotate the circular disc along the ray till point A again touches the ray. Mark that point on the ray as Q.

•Line segment AB is the diameter (d) of the circle. Measure AB. •Length PQ is the circumference (c) of the circle. Measure PQ
.Find the ratio of c/d
