A circle with a radius (d/2) of 2.1 feet has a circumference of 13.2 feet.
Its radius is: 17.27/(2*pi) in feet
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
radius = 54/(2*pi)
radius in feet = 13/(2*pi)
The circumference is 12.566370614359172 feet.
A circle with a radius (d/2) of 2.1 feet has a circumference of 13.2 feet.
A circle with a radius of 0.5 feet (d/2) has a circumference of 3.1 feet.
Its radius is: 17.27/(2*pi) in feet
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
Circumference = 2*pi*2 feet or as 4*pi feet
The circumference of a circle with a radius of 6 feet is about 37.7 feet. (C = r x 2 x Pi)
