Question

A wire when bent in form of square enclosee an area of 484cm.What will be the enclosed area when same wire is bent into form of circle

Answer 1

Answer:

616 cm²

Step-by-step explanation:

Area of Square = (side)²

484 = (side)²

side = √484

= 22 cm

Perimeter of the square = Circumference of the circle

[ As the same wire will have the same length ]

Circumference of Circle = 4 × 22 = 88cm

2 π r = 88

r = 88 / 2 × 3.14 = 14.01 ( approx 14 )

Area of the circle = πr²

= 3.14 × 14 × 14

= 616 cm²
