Question

A wire in the shape of a square of side 88 cm is bent so as to form a circular ring. Find the area of the circle.

Answer 1

I think area of the circle is equal to the square's area.

Answer 2

Answer:

The area of the circle is 616.31 centimeter square.

Step-by-step explanation:

Given : A wire in the shape of a square of side 88 cm is bent so as to form a circular ring.

To find: The area of the circle?

Solution :

Length of the wire is 88 cm when it is bent in the form of circle the length will become the circumference of the circle.

Now circumference of the circle is 88 cm.

$C=2\pi r$

$88=2(3.14) r$

$r=14.01cm$

The area of the circle is $A=\pi r^2$

$A=(3.14)(14.01)^2$

$A=(3.14)(196.2801)$

$A=616.31 cm^2$

Therefore, The area of the circle is 616.31 centimeter square.
