Question

a wire is in the shape of square with each side of 16.5 CM is bent in the shape of a circle find the circumference and diameter of the circle​

Answer 1

ATQ, the wire which was in shape of a squy with each side 16.5cm was bent in the shape of a circle.

therefore perimeter of the square = circumference of the circle.

given the side if the square = 16.5cm

perimeter of the square = side × 4

= 16.5 × 4

= 66cm

therefore the circumference of the circle is also 66cm.

>> 2πr = 66cm

>> 2 × 22/7 × r = 66cm

>> 44/7 × r = 66cm

>> r = 66/1 × 7/44

>> r = 1.5 × 7

>> r = 10.5cm

radius of the circle is 10.5cm.

we know that the diameter of a circle is double the length of it's radius.

hence, it's diameter = 10.5 × 2 = 21cm
