Question

a wire is in the shape of a circle of radius 10 cm, it is regent to form a square. find the side of the square so formed​

Answer 1

Answer:

• circumference of circle=2pier
• 2(pie)r=2×pie×10=20pie
• let side of the square =x
• 4x=20pie
• x=5pie.
• so,side of square is 5pie

Answer 2

Answer:

approximately 15.7cm

Step-by-step explanation:

In this case, circumference of circle is equal to perimeter of square.So, 2πr =4s.2πr=2*3.14*10cm I.e 62.8cm.So,62.8cm=4s.Then s=62.8cm/4.So,s=15.7cm
