Question

from the marked point back to
You can also find the distance by putting a string on the edge
Fig 11.30
of the circular object and taking all round it
The distance around a circular region is known as its circumference,
We
THIS
Take a bottle cap, a bangle or any other circular object and find the circumference,
Now can you find the distance covered by the athlete on the track by this method?
Still, it will be very difficult to find the distance around the track or any other circular
object by measuring through string. Moreover, the measurement will not be accurate,
So, we need some formula for this, as we have for rectilinear figures or shapes,
Letus sceif there is any relationship between the diameter and the circumference of
the circles
Consider the following table: Dawicieles of different and and fmd their circumference
by using string. Also find the ratio of the circumference to the drameter
Circle
Radius
Diameter
Circumference
Ratio of Circumference
to Diameter​
