The circumference of a circle is 6.28. What is the area of the circle?

The circumference of a circle = 2πr (where r denotes the radius of the circle)

Answer: The area of the circle whose circumference is 6.28, is 3.14 square units

The area of a circle = πr²

Explanation:

For the given circle, 2πr = 6.28 units

Taking π = 3.14

2 × 3.14 × r = 6.28

r = 1

Area of the given circle = πr² = π(1)²

Area = 3.14 sq units

Hence, the area of the circle whose circumference is 6.28, is 3.14 square units.
