What is the diameter radius circumference and are of a circle with a diameter of 80 ft?

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. :)
