Answer 1

Given:-

• $\sf\purple{area \ of \ the \ square⟶}$ 121 cm²

To find:-

• Area of the circle.

Solution:-

$\sf\blue{↬}$ side of the square

$\sqrt{121} \: cm \: = 11 \: cm$

$\sf\blue{⟶}$ Perimeter of the square = (11×4) cm = $\sf\orange{44 \ cm}$

$\sf\blue{↬}$ circumference of the circle = perimeter of the square = $\sf\orange{44 \ cm}$

◕ Let, the radius of the circle be r cm.

$2 \: \pi \: r = 44 = 2 \times \frac{22}{7} \times r = 44$

$= > \: r = (44 \times \frac{7}{44}) = 7$

$\sf\red{area \ of \ the \ circle}$$\sf\red{↬}$

$\pi \: r \: 2$

$= ( \frac{22}{7} \times 7 \times 7)cm \: 2 = 154cm2$

$\sf\green{Hence \ the \ area \ enclosed \ by \ the \ circle \ is \ 154 \ cm²}$
