Formula nesessary ​

Answer 1

Step-by-step explanation:

∴ The circumference of the circle=2πr=44cm

⇒2×7/22

r=44⇒r=2×22

44×7=7cm

Now, Area of the circle=πr

2= 7

22×7×7=154cm

Now the wire is converted into square,

Then perimeter of square=44cm

⇒4× side=44

⇒ side= 4

44=11cm

Now, area of square=side×side=11×11=121cm 2

• 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
