The circumference of a circle us 6.28 what is the area of the circle

Use the formula of circumference to find the diameter of the circle.

C=3.14D

6.28=3.14D

divide both sides by 3.14

D=2 Radius =1 because the radius is half of the diameter

Now, we will use the area of a circle formula: A=3.14 R^2

A=3.14(1)^2

A=3.14x1

A=3.14 that is the area of the circle.

3.14

Step-by-step explanation:

choice b is correct

step-by-step explanation:
