Question

The circumference of a circle is 132 m. Find its area.​

Answer 1

Answer:

1386 m²

Step-by-step explanation:

The circumference of circle is 132

2πr=132m

r=132×7/44 m  

r=21m

The area =πr²

22/7×21×21 m²

66×21 m²

=1386 m²

Answer 2

Given :

• Shape = Circle
• Circumference of Circle = 132m

To Find :

• Area of Circle

Solution :

Finding the Radius of Circle :

⠀⟶⠀Circumference of Circle = 2πr

⠀⟶⠀132 = 2 × 22/7 × r

⠀⟶⠀132/2 = 22/7 × r

⠀⟶⠀66 = 22/7 × r

⠀⟶⠀66 × 7 = 22 × r

⠀⟶⠀462 = 22 × r

⠀⟶⠀462/22 = r

⠀⟶⠀21m = radius

Finding the Area of Circle :

⠀⟶⠀Area of Circle = πr²

⠀⟶⠀Area of Circle = 22/7 × (21)²

⠀⟶⠀Area of Circle = 22/7 × 21 × 21

⠀⟶⠀Area of Circle = 22 × 3 × 21

⠀⟶⠀Area of Circle = 66 × 21

⠀⟶⠀Area of Circle = 1386m²

⛬ Area of Circle is 1386m²
