Question

Que: A circular park of radius 20m is situated in a colony. Three boys Ankur, 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

Answer:

Radius is 20 m

Circumference= 2*22/7*20

=880/7 m

Distance between each boy=880/7*1/3

=880/21

=41.91 m

I am not sure, It may be incorrect.

Thanks.

Answer 2

Step-by-step explanation:

First, let us take out the Circumference of the circular park.

Given, radius = 20m and we know, value of pie is 3.14

The circumference of the circle = 2 * pie * radius of the circle

Applying all values, = ( 2 * 3.14 * 20 ) cm

The circumference of the circle is 125.6 cm

Now, since there are three boys sitting in equal distances..

So, let us divide the circumference of the park by number of boys

So, as per the statement, circumference of the circular park / no. of boys = length of each string

Applying all values, 125.6 / 3 = 41.866...cm= 41.87 cm approx.
