Question

The area of a square is 100cm.calculate the circumference of the largest circle cut out of it.

Answer 1

Area of square is 100cm²

(Side)²=100

Side=10cm

So,radius=5cm,since side become diameter

Circumference of circle=2πr

=2×3.14×5

=31.4cm

Answer 2

The circumference of the largest circle is 31.43 cm.

Step-by-step explanation:

Since we have given that

Area of square = 100 sq. cm.

So, side would be

$\sqrt{Area}=\sqrt{100}=10\ cm$

So, Diameter = 10 cm for the largest circle cut out of it.

So, radius = 5 cm

So, the circumference of the largest circle would be

$2\pi r=2\times \dfrac{22}{7}\times 5=31.43\ cm$

Hence, the circumference of the largest circle is 31.43 cm.
