Question

a wire is in a circular shape of radius 28cm if it is sent in the form of square what will be the area of the square formed

Answer 1

Answer:

1936 cm^2

Step-by-step explanation:

circumference of circle = 2pieR

2*(22/7)*28

= 44*4 cm

circumference of square = 4* side

4*side = 44*4

side = 44 cm

area = side^2

area = 44^2

= 1936 cm^2

Answer 2

Answer:

Area of square = 1936cm²

Step-by-step explanation:

Radius = 28cm

Circumference of Circle = 2πr

                                        = 2×(22/7)×28

                                        = 2×22×4

                                        = 176 cm

From the same wire a square is formed

therefore,

Perimeter of square = Cicumference of Circle

                             4a = 176cm

                               a = 44cm

Area of square = a²

                (44)² = 1936cm²
