less than 3
more than 3
equal to 3
none of the above
14. A wire is bent to form a square of side 22cm. If the wire is rebent

Answer 1

Answer:

1) Ratio of Circumference : Diameter is more than 3

2) 22 × 4 = 88 cm

Explaination:

1) Circumference = 2πr

• => 2π(d/2) because r = d/2
• => πd that is 2 and 2 get's cancelled
• and
• Diameter = d
• Now
• Circumference : Diameter
• πd : d
• Removing d.
• π is left out
• and π = 3.14 which is greater than 3

2) one of the side = 22cm

• now if we open the square
• we have 4 sides
• therefore
• 4× 22 = 88 cm

therefore 88cm is the length of the wire
