Question

3. A wire of length 176 cm is first bent into a square and then into a circle. Which one will have more area?​

Answer 1

Answer:

perimeter of sq=4S

176=4S

176/4=S

44=s

area of sq=1936

p of circle=2*22/7*r

176=44/7*r

176*7/44=r

28

a of circle=22/7*28*28

=2468

circle has more area

Answer 2

circumference of circle=176

2πr=176

r=28

area of circle= πr²

=22/7*28*28

=22*4*28

=2464cm³

perimeter of square = 176

4s=176

s=44

aree of square = s²

=1936cm³

circle has more area
