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
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.
