Question

A human chain is made for the awareness of Covid 19 Pandemic on India Gate by the students in the form of circle
Q1 The radius of the circle is 56m. If each student is given 2m space to stand, then how many students will be their in the chain?
Q2.If outside the circle there is an another chain of students in the form of square in such a manner that circle is inscribed in square ,then what is the side of the square?

Answer 1

given

radius = 56 m

circumference of circle = 2πr

= 2*(22/7)*56

= 2*22*8

= 352 m

every student got 2 m to stand

number of students = 352/2

= 176

2). the side of square in which the circle is inscribed is equal to the diameter of the circle

side = 2r = 2*56 = 112 m

Answer 2

Step-by-step explanation:

1) the parameters of the circle is = 2* 22/7 *56 m

= 2*22*8 m = 352 m

so the number of the student is =352/2 = 176

2)

the side of the square is equal to the diameter of the circle .

show the side of the square is= 2*56 m= 112 m
