Question

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

Answer 1

Answer:

the answer is as follows

Step-by-step explanation:

the perimeter of square = perimeter of the circle

$2\pi r$ = 22

2 *22/7 *r = 22

r = 7/2 CM

AREA = $\pi R^{2}$

             = 22/7*49/4

               = 38.5  $cm^{2}$

Answer 2

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
