Question

A wire is bent to form a circle of radius 49 cm.If the same wire is bent to form a square,what will be its area​

Answer 1

Answer:

first find the circumference of circle with r=49cm

then perimeter of there is equal to circumference of circle when you get the circumference of circle put in the formula that perimeter of square is equal to 4 into s what is the value of the circumference you put in the parameter and then divide by 4 you will get the side and then you can find the area by formula as into

Answer 2

Solution :-

→ Radius of circle = 49cm.

→ circumference of circle = 2πr = 2 * (22/7) * 49 = 308cm.

Now, it has been said that same wire is bent to form a Square .

So, we can conclude that, perimeter of square will remain same.

Therefore,

→ Perimeter of Square = 4 * side = 308cm

→ side of Square = (308/4) = 77cm.

Hence,

→ Area of Square = (side)² = (77)² = 5,929 cm² (Ans.)

ஃ Area of Square will be 5,929cm².
