If the circumference of a circle is 10 feet the radius is: about 1.592 feet. For this type of calculation, divide the circumference by Pi (about 3.1416). This gives you the diameter. Next, divide the diameter by two to get the radius.
The circumference of a circle with a diameter of two is about 6.28
Circumference= 37.68 feet. All you have to do is multiply the diameter by pi. Same with radius. Multiply the radius by two to get the diameter then do diameter times pi.(pi= 3.14 or 22 over 7.)
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
well the circumference is equal to pi times the diameter, so all that you have to do is divide the circumference by pi to get the diameter. Then you divide the diameter by two to get the radius.
To find the circumference of a circle you multiply the diameter by pi (3.14), the diameter is two times the radius.
Circumference of circle: 6*pi = 18.85 feet rounded to two decimal places
The circumference also doubles.
You divide the circumference by Pi (about 3.1416). This gives you the diameter. Divide the diameter by two to get the radius.
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
If the circumference is 37 inches then the diameter is 37/pi = 11.78 inches rounded to two decimal places
The formula for the circumference of a circle is 2.pi.r where r= the radius, since the diameter is 2.r (two times the radius),the circumference will be pi.diameter. pi=3.14159... so for a diameter of 34mm the circumference=pi.34=106.8mm
