The circumference of a 128-foot diameter circle is: 402.12 feet.
diameter = 128/pi
128 divided by pi (approx. 3.1415927) = about 40.743 feet.
128=2πr 128/2π=r r=20.37 Diameter is equal to twice radius Therefore 20.37 times 2 40.74
Diameter of a circle = circumference/pi
The circumference of a 128-foot diameter circle is: 402.12 feet.
diameter = 128/pi
If the circumference is 128 feet, the radius is 20.37 feet. If the diameter is 128 feet, the radius is 64 feet.
128 divided by pi (approx. 3.1415927) = about 40.743 feet.
The formula for the circumference of a circle is 2*pi*radius or pi*diameter. In this case, it's 128=pi*d. Solve for d, and you get 40.74 feet.
Diameter- 128 / pi = 40.7436654 or 41 feet, I had this on my homework, do you know how to show the work though? Tricky.
128=2πr 128/2π=r r=20.37 Diameter is equal to twice radius Therefore 20.37 times 2 40.74
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
