Answer 2

Answer:

• The area of the circle = 5544 m²

Given:

• Circumference of the circle is 264 m.

Need to find:

• The area of the circle = ?

Solution:

Circumference of circle = 264 m

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀2πr = 264 m

⠀⠀⠀⠀⠀⠀ ⠀2 × 22/7 × r = 264 m

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀r = 264 × 7 / 22 × 2

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀r = 42 m

Formula used here:

• Area of circle = πr²

Putting the values:

➜ Area of circle = 22/7 × 42 × 42

➜ Area of circle = 22 × 6 × 42

➜ Area of circle = 5544 m²

Therefore:

• The area of the circle is 5544 m².
