So finally you see why math is important? Area=Pi X R X R where Pi=3.14159 R=radius of the circle. Lets say the circle is 2 feet in diameter. Then the area is Area=3.14159 X 1 X 1=3.14 Square Feet. Cool huh?
441pi/4 sq ft
(60,000 sq ft) / (43,560 sq ft / acre) = 1.3774 acre (rounded)
Area 36 ft diameter circle = pi x radius squared = 3.1416 x 18 ft x 18 ft = 1017.87 sq ft
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 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).
441pi/4 sq ft
132.7 sq ft, approx.
This would not be called a circle. IT would be called a ring. Sq Ft of outer ring - Sq Ft of inner ring = Sq Ft in between 113.04 - 12.56 = 100.48 sq ft
(60,000 sq ft) / (43,560 sq ft / acre) = 1.3774 acre (rounded)
a 24 inch circle is a 2 ft diameter circle, or a 1 ft radius circle. the area of a circle is pi * r squared, so 1 ft squared is 1 sq ft. Times pi (=3.14159) is 3.14159 sq ft
Area of 30 inch circle = pi*302 sq inches Area of 18 inch circle = pi*182 sq inches Difference = pi*(302 - 182) = 576*pi sq inches 1 sq foot = 1 ft*1 ft = 12 inches*12 inches = 144 sq inches so 576*pi sq inches = 576/144 *pi sq ft = 4*pi sq ft = 12.57 sq ft.
The answer is in the question! 12 sq ft!
Area 36 ft diameter circle = pi x radius squared = 3.1416 x 18 ft x 18 ft = 1017.87 sq ft
the questions is asking you to find the area, so the area of a circle is 3.14r^2. Plug 8ft for radius and you get your answer to be approximately 201.06 sq ft
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.
