Question

a wire when bent in the form of a square encloses an area of 196 CM ^2 if the same wire is bent to form circle find the area of the circle​

Answer 1

Answer:

I think answer is 16cm..........................????

Answer 2

Answer:

Hey mate!

The answer is 249.45 cm^2

Step-by-step explanation:

Area of Square = 196 cm2

Side of Square = √Area = √196 = 14 cm

Perimeter of Square = 4 x 14 cm

i.e. length of wire = 56 cm

Circumference of circle = 56 cm

2πr = 56

2 × 22/7 × r = 56

r = (56 × 7)/(2 × 22)

r = 98/11 cm

∴ Area of circle enclosed = πr^2

= 22/7 × 98/11 × 98/11

= 2744/11

249.45 cm^2
