Answer:

area of the circle = 3.14 square units

Step-by-step explanation:

Circumference of the circle formula is [tex]2\pir[/tex]

where r is the radius of the circle

given circumference = 6.28

[tex]2\pir[/tex] = 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 = [tex]\pi r^2[/tex]

= 3.14 *1*1 = 3.14
