Question

A copper wire of length 44cm is to be bent into

a square and a circle. Which will have a larger

area? ​

Answer 1

Step-by-step explanation:

we have to first find the radius and the side of the square measures

circle: circumference=2πr

44=2*22/7*r

r=44*7/22

r=14/2

r=7 cm

square = perimeter = side *4

44=side * 4

side=44/4

side=11

area of circle

πr²

22/7*7*7

22*7=154

area of square = side² or side *side

area = 11² or 11*11

area = 121

area of square ∠ area of circle

121 ∠ 154

therefore area of the circle is greater than area of square

Answer 2

$\LARGE{ \underline{\underline{ \pink{ \bf{Required \: answer:}}}}}$

Wire of length which is bent = 44cm

Therefore,

Perimeter of = perimeter of circle = 44cm

Let's find side of square by using perimeter =

p = 4 × Side

44 = 4 × Side

Side = 11

Area = Side × Side

Area = 121 cm²

Let's find radius of circle by using perimeter =

p = 2 π r

44 = 2 × 22/7 × r

r = 7 cm

Area = π r²

Area = 22/7 × 7 ×7

Area = 154 cm²

As we got area of square = 121 cm² and area of circle = 154 cm²

So, circle will have larger area
