I'm sorry the question isn't clear enough. A four foot diameter? radius? area?
NO
Area of a circle = pi*radius squared
72 foot
A 25-foot radius circle is 1,963.5 ft2

The circumference of a circle with a radius of four is: 25.13
A four-inch radius circle has an area of about 50.27 square inches.
Area of a circle = pi times radius squared

72 foot
The radius of a circle is half the length of the diameter. Therefore, if the diameter is 1 foot, the radius would be 0.5 feet. This is because the radius is the distance from the center of the circle to any point on the circle's circumference, while the diameter is the distance across the circle passing through the center.
The circumference of circle with 2 foot radius is: about 12.57 feet. (c = r x 2 x Pi)
The circumference of a circle with a 4-foot radius is about 25.13 feet. (C = r x 2 x Pi)
