A 25-foot radius circle is 1,963.5 ft2
The area of a circle is PI times the radius of the circle squared. The radius of a one foot diameter circle it 1/2 or .5 feet. .5 squared is .25 PI is 3.1416 3.1416 times .25 = .79 square feet So, there are about .8 square feet in a 1 foot diameter circle.
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
The circumference is 565.5 feet. The area is 25,450 square feet. The diameter is 180 feet.
You take half the area of a circle in square feet. The formula is: 1/2 * pi * (radius)2
A = 1,767,100 square feet.
Area of the circle in square feet: pi*radius squared
Area of a circle with a 4 feet radius = 16*pi square feet
A 25-foot radius circle is 1,963.5 ft2
That would be 5026.55 square feet.
Area of circle: pi*22 squared = 484*pi square feet
Area of the circle in square feet = pi times radius squared
The area of a circle is PI times the radius of the circle squared. The radius of a one foot diameter circle it 1/2 or .5 feet. .5 squared is .25 PI is 3.1416 3.1416 times .25 = .79 square feet So, there are about .8 square feet in a 1 foot diameter circle.
You want the area of a circle, which is pi*r2 Just make sure your radius (r) is in feet and you answer will be square feet.
28.27 ft2
78.54 ft2
Area = pi*r2where r is the radius of the circle.A 2-foot circle has a radius of 1 ft so area = pi square feet ie 3.14 sq feet, approx.Area = pi*r2where r is the radius of the circle.A 2-foot circle has a radius of 1 ft so area = pi square feet ie 3.14 sq feet, approx.Area = pi*r2where r is the radius of the circle.A 2-foot circle has a radius of 1 ft so area = pi square feet ie 3.14 sq feet, approx.Area = pi*r2where r is the radius of the circle.A 2-foot circle has a radius of 1 ft so area = pi square feet ie 3.14 sq feet, approx.
