Question

A wire is in the form of a circle of radius 63 cm. The same wire is used

to make a square. Find the side of the square so formed. Find which

one has more area.​

Answer 1

Step-by-step explanation:

to get the length of the wire we need circumference of the circle

so,

circumference = 2πr

= 2 * 22/7 * 63

= 2 * 22 * 9

= 396 cm

so to make a square we need 4 equal parts so simply divide it by 4

396/4 = 99cm

so each side is of 99cm

area of circle is = πr²

= 22/7 * 63 * 63

= 22*9*63

=12474 cm²

area of square = (99)²

= 9801 cm²

the area of circle is always grater than area of square though the length of wire is same

Answer 2

Answer:

Step-by-step explanation:

so we should first know the circumferance  of the circle

2 π r

2 ×22/7×63

2×22 × 9

44×9

396

4a =396

a=396/4

a=9

find the area of the square
