Answer 1

Answer :

• Circumference of circle = 66cm.
• Diameter of circle = 21cm.

Step-by-step explanation :-

To Find,

• The circumference
• The diameter of the circle.

Solution,

Given that,

• Side of Square = 16.5cm

Therefore, perimeter and square is,

As we know that,

Perimeter of square = 4 × side

» 4 × 16.5

» 66cm

Perimeter of Square = Circumference of circle,

As, a wire in the shape of square is bend into the shape of a circle,

Hence, the circumference of circle is 66cm.

Now, let's us find out the radius of circle,

Let us assume the radius as r,

» 2 × 22/7 × r = 66

» r = { 66 × 7 } / { 22 × 2 }

» r = { 3 × 7 } / 2

» r = 21 / 2

» r = 10.5

The radius of circle is 10.5cm.

Now, diameter is,

As we know that,

Diameter = 2 × Radius

» 2 × 10.5

» 21cm

The diameter of circle is 21cm.
