Diameter of a circle = circumference/pi
25.464
It has a circumference of 251.33 inches.
Diameter: Well, you said it yourself, 80 feet. Diameter is the distance across the widest part of a circle. Radius: The radius of a circle is half of the diameter, so in this case, it would be 40 feet. The radius is the distance from the center of the circle to the outside. Circumference: The formula for circumference is Pi (3.14 or 22/7) times the diameter. In this case, it would turn out to be 251.2 feet. Area: The formula for the area of a circle is Pi time the radius squared. So, you square the radius and multiply that by Pi (3.14). In this case, it would be 15775.36 feet squared. I hope I made sense. :)
you do 80 divided by 2 divided by (pie) 3.14 wich gives you the radius..and then times the radius by two..
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
Circumference of a circle = π × diameter = π × 80 mm = 80π mm ≈ 251 mm
Diameter = 80/pi feet
The diameter is about 25.464 units.
25.464
It has a circumference of 251.33 inches.
80/pi = 25.465 cm (rounded)
divide it by three. that gets it close.
Circumference = Pi x d: 3.14 x 80 = 251.2 feet
If circumference = 160', and circumference = 2 x pi x r, then... 160 = 2 x pi x r 80 = pi x r 80/pi = r 2(80/pi) = diameter = 50.99'
