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.
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.
Area of the circle = pi*7.82 = 191.134497 Approximate area = 3*82 = 192
The approximate area of a circle with a diameter of 60 centimeters is 2,827.43 square centimeters.
The approximate area of a circle with a 12-inch diameter is: 113 square inches.
Area of the circle is about 10 square units
Approximate area of a 15 foot radius circle is a little more than 700 square feet.
For a circle, area = pi x radius2, where pi is approximate 3.14.
A circle with a radius of 11m has an area of ~380.13 m2
The area is about 64 pi.
Area of circle: pi*1.8^2 = about 10 square units
About 153.86 square in. To find out the area of a circle do: r^2*pi.
