Question

A circular park of radius 20m is situated in a Colony. Three boys Ankara, Syed and David are sitting at equal distance on its boundary each having a toy telephone in his hands to talk each other. find the length of the string of each phone.

Answer 1

let the distance between each boy be x
consequently length of the string also equal to x.

CIRCUMFERENCE=2πr

$= 2 \times \frac{22}{7} \times 20$

$= \frac{22}{7} \times 40$

$= 22 \times 5.71$

=125.62m


x+x+x=125.62
3x=125.62
x=125.62/3
x=41.87m


the length of the string is 41.87m
