You don't mention whether the 4 feet is the circumference, diameter or radius.
The area of a circle is pi times the radius squared.
If 4 feet is the circumference, the area is about 1.3 feet squared.
If 4 feet is the diameter, the area is about 12.6 feet squared.
If 4 feet is the radius, the area is about 50.3 feet squared.

One problem with using rectangles to approximate an area under a curve is it will overestimate or underestimate the area, depending on which endpoint is used. The trapezoidal method gives a closer approximation.
The approximate length multiplied by the approximate width.
Count the number of squirrels in a small area. maybe one acre. Then multiply by the entire area of the forest.
what is the approximate area of a circle with a radius of 26ft
The approximate area of the circle lies between the areas of the circumscribed and the inscribed hexagons.
The approximate surface area of a sphere with circumference 37.68km is 452km
Area of the circle = pi*7.82 = 191.134497 Approximate area = 3*82 = 192
There are many approximation methods for area.
The approximate area of the shaded region of 10 cm is 100 square centimeters.
The approximate area of a circle with a 12-inch diameter is: 113 square inches.
The approximate area of a circle with a diameter of 60 centimeters is 2,827.43 square centimeters.
