Question

a wire in the shapes of a square of side 11cm is cut and rebent in the form of a circle find the area enclosed by the circular wire

Answer 1

answer is 162 cm square

Answer 2

The area of circle is 154 cm².

Step-by-step explanation:

Consider the provided information.

The side of square  11 cm  long.

It cut and re-bent in form of a circle.

When we change the shape area will also change but perimeter remains constant.

Perimeter = Length of wire = 4×11 = 44

Circle circumference = Perimeter of square

$2\pi r =44$

$2\times\frac{22}{7}\times r =44$

$r =7$

The radius of the circle is 7 cm.

Now find the area of the circle using the formula: $A=\pi r^2$

$A=\frac{22}{7}\times 7^2$

$A=22\times 7$

$A=154$

Hence, the area of circle is 154 cm².
