Answer:
area of the circle = 3.14 square units
Step-by-step explanation:
Circumference of the circle formula is ![2\pir](https://tex.z-dn.net/?f=2%5Cpir)
where r is the radius of the circle
given circumference = 6.28
= 6.28
Value of pi is 3.14
2*3.14 * r= 6.28
6.28 r = 6.28
divide by 6.28 on both sides
r = 1
radius = 1
Area of the circle = ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
= 3.14 *1*1 = 3.14
