Question

Find the area of a circle made of 44 cm wire ?
​

Answer 1

Answer:

circle perimeter = 2*pi*r =44

r= 44* 7/22 *1/2 = 7 cm

area = pi*r^2 = 22*7=154 cm^2

perimeter of square = 4a =44 =a=11

area of square = 11^2 =121 cm^2

difference is = 154-121 =33 cm^2

Answer 2

Answer:

Given, Total length of the wire=44cm

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

⇒2×722×r=44

⇒r=2×2244×7=7cm

Now, Area of the circle=πr2=722×7×7=154cm2
