If the diameter of the circle is 4 feet across the area is about 12.6 sq ft. You can check this by using the formula Area=Pi times the radius squared.
The area of a circle with a 13 ft diameter is: 132.7 square feet.
Area of a circle = pi*radius2
If the circle is 20 ft radius, the area is π·20² = 1256.637 ft² If the circle is 20 ft diameter, the area is π·(20/2)² = 314.1593 ft² If the circle is 20 ft circumference, the are is π·(20/2π)² = 63.66198 ft²
The area of a 5 foot circle is: 19.63 square feet.
If the diameter of the circle is 4 feet across the area is about 12.6 sq ft. You can check this by using the formula Area=Pi times the radius squared.
diameter=18 ft so radius=9 feet area of cirlce=pi*r^2 so area is 81pi ft^2 =81*3.14 ft^2 =254.34 ft^2
The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).
The area is the same as that of a big 20 ft circle. Assuming the 20 ft refers to the diameter of the circle, its area is 314.159 sq ft (to 3 dp)
Area of circle = Pi x diameter2/4 = 153.96 sq ft for a 14 ft circle
The area of a circle that has a 10 ft diameter is: 78.54 square feet.
The area of a circle with a 13 ft diameter is: 132.7 square feet.
Area of a circle = pi*radius2
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or pi*diameter
If the circle is 20 ft radius, the area is π·20² = 1256.637 ft² If the circle is 20 ft diameter, the area is π·(20/2)² = 314.1593 ft² If the circle is 20 ft circumference, the are is π·(20/2π)² = 63.66198 ft²
Area of a circle = pi times radius squared
A circle 74 feet across has a radius of 37 feet. using the formula Area = pi * r2 , the area equals (3.1416)x(372) = 4300.8405 sq ft.
