You should clarify whether "1-foot circle" refers to a circle with a radius of 1 foot, a diameter of 1 foot, or a circumference of 1 foot. The circumference of a circle is equal to the diameter times pi (approximately 3.14).
To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
The circumference of a circle if the diameter is 1 equals 3.1412 (π).
The circumference of a circle with a diameter of 1 is Pi: 3.1416
If a circle has a circumference of 3.14 (pi) the diameter is: 1
The formula is pi times diameter. If the diameter is 1 foot, times 3.14, the circumference will be 3.14 feet.
The circumference of any circle is (pi) x (its diameter). If diameter = 1 then Circumference = pi .
d = 1 foot (0.99949)
The circumference of a circle if the diameter is 1 cm will be Pi (about 3.1416).
The diameter of a circle whose circumference is 314 is about 1 (99.95).
Because the circumference of a circle = pi*diameter and pi*1 = pi
If a circle has a radius of 1, the diameter is 2, and the circumference is 6.28 (approximately).
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
A circumference of 3.14 inches.
Circumference = pi x diameter. So the circumference of a circle with diameter 12 cm = pi x 12 = 37.7 cm (1 decimal place.)
diameter is about 1 radius is about 0.5
Circumference of any circle = 2*pi*radius or diameter*pi
