Question

A wire is in the form of a circle of radius 42 cm. It is
bent into a square. Determine the side of the square.​

Answer 1

Answer:

Explanation:

the length of the wire = the perimeter of the circle = 2πx42 = (44x6)cm. the perimeter of the square = the length of the wire = 44x6 cm. Hence the length of the sides of the square = 44x6\4 = 66cm

Answer 2

Answer :

The side of square is 66cm.

Step-by-step explanation :-

To Find:-

• The side of a square

Solution:-

Given that,

• Radius of circle = 42cm
• A wire in form of circle is bent to form a square

Therefore,

Perimeter of square = Circumference of circle,

The circumference of the circle is,

As we know that,

Circumference of circle = 2πr, therefore,

» 2 × 22/7 × 42

» 2 × 22 × 6

» 44 × 6

» 264cm

The circumference of circle is 264cm & the perimeter of square is 264cm.

The side of square is,

As we know that,

Perimeter = 4 × side, therefore

» 4 × side = Perimeter

» 4 × side = 264

» side = 264 / 4

» side = 66

Therefore, the side of square is 66cm.
