Question

6) A wire is in the shape of a square of with side 22 cm. It is bent to form a circle. Find the area of the circle​

Answer 1

Solution :

➤ The side of the square formed using a wire is 22 cm

★ Circumference of circle = Perimeter of square

→ 2πr = 4a

→ 2 × 22/7 × r = 4 × 22

→ 44/7 × r = 88

→ r = 88 × 7/44

→ r = 14 cm

The radius of the circle is 14 cm

★ Area of the circle = πr²

→ Area = 22/7 × 7 × 14

→ Area = 22 × 7 × 2

→ Area = 308 cm²

∴ Area of the circle is 308 cm²
