radius = 40/(2*pi) in inches
Circumference of any circle = 2*pi*radius or diameter*pi
The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter is 40 feet. So, the circumference would be C = π(40) = 40π feet, or approximately 125.66 feet.
Radius: 40/2pi = 6.366197724 Area: pi*6.366197724 squared = 127.324 square feet rounded
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. :)
The radius of a circle whose circumference is 40pi is 20 units.
radius = 40/(2*pi) in inches
Circumference of any circle = 2*pi*radius or diameter*pi
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. Given a diameter of 40 feet, we can plug this value into the formula to find the circumference: C = π(40) = 3.14159(40) = 125.6636 feet. Therefore, the circumference of a circle with a diameter of 40 feet is approximately 125.66 feet.

Circumference = Pi x d: 40 = 3.14 x 40 = 125.6 feet
The circumference of a circle is calculated using the formula C = 2πr, where r is the radius of the circle. In this case, the radius is half of the diameter, so it would be 15 feet. Plugging this into the formula, we get C = 2π(15) = 30π feet. This is approximately 94.25 feet around a 30-foot circle.
About 40 feet. Circumference = 3.14 x diameter
Diameter = 2 * radius So in this case, 40 feet.
1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
