Question

a wire is in the form of circle of radius 42cm if it is bent into a square find the side of square

Answer 1

Answer:

66 cm

Step-by-step explanation:

Find the circumference:

circumference = 2πr

circumference = 2π(42) = 264 cm

Find the length of the square:

Perimeter = 264 cm

Perimeter = 4 x Length

4 x Length = 264

Length = 264 ÷ 4 = 66 cm

Answer: The length of the side is 66 cm

Answer 2

Let radius of circle be r
then
Circumference of circle be 2πr
And side of square be x
Then perimeter of square be 4x
ATQ
2πr=4x
2*22/7*42=4*x
2*22*6=4x
264/4=x
66=x
Then, side of square=66cm
