An artist used silver wire to make a square that has a perimeter of 40 inches. She then used copper wire to make the largest cir

JulijaS [17]

The area of the copper circle A= 69.08 $inches^{2}$ .

<u>Step-by-step explanation:</u>

Given data,

Perimeter of the Square =40 inches.

Let us find the measurement of one side.

The formula for perimeter of a square is 4a.

where a is length of one side of a square.

We know that perimeter of the square is 40.

∴ 4a=40.

a=10 inches.

Imagine that moving one side of the square into the circle.

You can observe that length of one side of square is the diameter of the circle.

∴Diameter of the circle =10 inches.

⇒ Radius of the circle r= 5 inches.

Area of the circle A= π $r^{2}$ .

A= 3.14×5×5.

Area of the circle A= 69.08 $inches^{2}$ .
