what is the calculation for the circumference of a circle?
219874
Students learn that the circumference of a circle is the distance around the circle, and the formula for the circumference of a circle is 2 times pi times the radius of the circle. Pi is the ratio of the circumference to the radius, which is approximately 22/7 or 3.14.

The Circumference of a circle or a sphere is equal to 6.2832 times the Radius. The Circumference of a circle or a sphere is equal to 3.1416 times the Diameter.

You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r.

Use the formula C/2π. Since the circumference is equal to πD, which is equal to 2πr, dividing the circumference by 2π will give the radius. If you have a sphere with a circumference of 20 m, find the radius by dividing 20/2π = 3.183 m. Use the same formula to convert between the radius and circumference of a circle.

Python Programming Code to Calculate Circumference of Circle # Python Program - Calculate Circumference of Circle print("Enter 'x' for exit."); rad = input("Enter radius of circle: "); if rad == 'x': exit(); else: radius = float(rad); circumference = 2*3.14*radius; print("\nCircumference of Circle =",circumference);

The diameter is always twice the radius, so either form of the equation works. This formula reads, “Area equals pi are squared.” Find the radius, circumference, and area of a circle if its diameter is equal to 10 feet in length. so the area is about 78.5 square feet.

Find formulas for the circle's radius, diameter, circumference and area , in terms of 'a'. As we've shown above, the circle's radius is equal to the half the length of the square's side, so r=a/2. The diameter is twice the radius, so d=a. The circumference is d ·π, so C=πa.

84.74 cm. The circumference of a circle if the area is 300 square centimeters. Area = pi*r^2 = 3.14*r^2 , area = 300 , r^2 = 300/3.14 = 95.5414 , r = 9.77cm , circumference =2 *pi*r =2*3.14*9.77 = 61.38 cm.

Solve the equation for the diameter of the circle, d= C/π. In this example, "d = 12 / 3.14." or "The diameter is equal to twelve divided by 3.14." Divide the circumference by pi to get the answer.

The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!

References: Circumference = 3.1416 * Dia. or 3.1416 * 2r: 3.1416 is (pi); Dia is the diameter and r is the radius.

Explanation: If the central angle measures 60 degrees, divide the 360 total degrees in the circle by 60. Multiply this by the measure of the corresponding arc to find the total circumference of the circle. Use the circumference to find the radius, then use the radius to find the area.

Learn that the perimeter of a circle has its own special name, called "circumference." The symbol is a capital C. It is calculated using the formula Pi x diameter, or 3.14 x d = C. It can also be calculated by Pi x (2 x radius) = C or 3.14 x (2 x r) = C. Learn about Pi.

That is, the circumference would be the length of the circle The area of a circle is pi (approximately 3.14) times the radius of the circle squared. The circumference is pi times the diameter if it were opened up and straightened out to a line segment.

To calculate the diameter of a circle, multiply the radius by 2. If you don't have the radius, divide the circumference of the circle by π to get the diameter. If you don't have the radius or the circumference, divide the area of the circle by π and then find that number's square root to get the radius.
