Question

A wire is in a circular shape of radius 25cm. if it is bend in the form a square what will be the area​

Answer 1

Answer:

Correct option is A)

Given radius of circle is 25 cm

Length of the wire will be equal to perimeter of the circle

⟹length of the wire is

2π(25)=

2×

3.14×

25=

157 cm

Now the wire is made in the form of a square

Let Length of the side of the square is s cm

As we know that

Length of the wire is equal to the perimeter of the square

⟹Perimeter of the square is 157 cm

⟹ 4s= 157⟹ s=

4

157

= 39.25 cm

Length of the side of the square is 39.25 cm

Answer 2

Step-by-step explanation:

Radius of circle, r=28cm

then the circumference = 2πr

=2×

7

22

×28

=176cm

Let a be the side of the square,

circumference of circle = perimeter of the square

176=4a

a=

4

176

=44cm

area of square = a

2

=44

=1936cm
