Question

a wire is of length 22 cm is bent in the form of a circle. Find the area of circle. Also , if the same wire we're bent in the form of square, would it's area be more or less ? (π=22/7)
​

Answer 1

Answer:

Area of circle = 38.5 sq. cm

Area of square = 30.25 sq. cm

Step-by-step explanation:

we know that,

circumference of circle = 2π×r

22=2×22/7×r

r= 22×7/22×2

r= 7/2

r = 3.5 cm

Area of circle = πr^2

= 22/7×3.5×3.5

= 38.5 sq. cm

perimeter of square =4× side

side = 22/4

side = 5.5 cm

Area of square = (side)^2

= 5.5×5.5

= 30.25 sq. cm
