Question

a wire in the form of a circle of radius 21 is bent into a square then the length of the diagonal of the square is​

Answer 1

A wire in the form of radius 21cm it is bent into a square ... we go in a depth, circumference of circle is equal to perimeter of square. ... So, perimeter of square= 132 ...

Answer 2

Answer:

Approx. 46.67 units

Step-by-step explanation:

Radius=21 units

π≈22/7

Circumference=2πr

                        =2×(22/7)×21

                        =2×22×3

                        =132 units

Perimeter of square=4s=132 units

⇒4s=132

⇒s=132/4=33

∴Side of the square=33 units

Diagonal of a square=(√2)×s

                                 =(√2)×33

                                 ≈46.67 units
