Question

A wire is in the form of a circle of radius 42cm.if it is bent in to a square find the side of a square ​

Answer 1

Answer:

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.

Step-by-step explanation:

Answer 2

Answer:

Area of square=πr²

=22/7×(42)²=5544cm²

So, Area of circle=area of square

Area of square= s²

5544=s²

So, s=√5544

s =74.45cm(aaprox)
