Area of a Circle = (pi)(r^2)
Diameter = 2r
If the diameter of the circle is 12, then the radius has to be 6.
If the area of a circle is pi times the square of the radius, and the square of 6 is 36 (6x6), then the area of the circle is 36pi.

The circumference and area of a circle with a 17 ft diameter are:C = 53.4 ftA = 227 ft2
Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle.
201.06ft2
Radius = diameter ÷ 2 Area = π x radius2 = π x (12 ÷ 2)2 = 36π ≈ 113 sq ft.
The area is 50.3 square feet.
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.
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).
There's no way to express area in feet - it needs to be square feet. A circle of radius 12" has an area of pi sq. ft. ~= 3.141 sq. ft. A circle of diameter 12" has area pi/4 sq ft ~= 3/4 sq. ft.
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or pi*diameter
A circle with a diameter has an area of 50.265486543928724876568901 sq. ft.

A circle with a diameter of 66 feet has an area of 3,421.19 square feet.
12 feet. The diameter of a circle is twice its radius.
Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle.
