Question

A wire is bent in shape of square of side 66cm . if the same wire is looped in form of a circle , what will be the radii of the circle​

Answer 1

Answer:

Length of wire = 4a

= 4 × 66 cm

= 264 cm

Now,

Circumference of circle = Length of wire

2 π r = 264 cm

r = (264 cm) / (2 π)

= 42 cm ………[Take π = 22/7]

Radius of circle is 42 cm

Answer 2

Answer:

r=42.038cm

Step-by-step explanation:

perimeter of a square=4a

here a =66cm

which means 4a=4*66=264

now area of the circle = 2 pie r

which means 264=2 pie r

ie,r=42.038cm

here pie=3.14
