Answer: Area = 12.57.
Step-by-step explanation:
The area of a circle is pi * radius^2.
the diameter / 2 = radius.
4/2=2 (2 is radius)
The radius should be 2. You put that into the area formula which is A=pi (2) ^2.
The area should be 12.57 and that is the final answer.

The area of a circle is pi * radius^2.
Diameter / 2 = radius.
4 / 2 = 2
The radius is 2. Plug this value into the area formula.
