Let's first find perimeter.
The perimeter of a circle is also known as the circumference.
Circumference = pi * diameter
Circumference = pi * 4
Perimeter = 4pi, or the approximate exact value: 12.57 meters
Now let's find area.
Area = pi * radius^2
Radius is half of the diameter, which in this case, 2.
Area = pi * 2^2
Area = 4pi, or the approximate exact value: 12.57 meters ^2
