Question

A wire is in shape of a circle are 154 cm2 if the wire is rebent to form a square then find the perimeter of squre

Answer 1

Answer:

308 cm

Step-by-step explanation:

Area Of the Circle = 154 cm²

                    πr² = 154

                       r = 49 cm

Perimeter of the Circle = 2πr = 2*π*49

                                      = 308 cm

So length of the Wire = 308 cm

It is stretch to the form of a Square which has four sides,

Whose perimeter =  4*a cm = Which is Equal to the Perimeter of the Circle,

Perimeter of the Square = 308 cm
