Question

a wire is in the shape of a square with side 22cm. it is bent to form a circle . find the area of the circle​

Answer 1

Answer:

616cm^2

Step-by-step explanation:

side of square = 22cm

perimeter of square = circumference of circle

so,

4 (22) = 2πr

4 × 22 = 2 × 22/7 × r

2 × 7 = r

r = 14cm

Now area of circle = πr^2

area = 22/7 × 14 × 14

area = 22 × 2 × 14

area = 22 × 28

area = 616cm^2
