If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
Diameter of a circle = circumference/pi
to find the circumference of any circle, times the diameter(d) by pi and you will get the answers.
circumference is π*d. In this case it is 8π feet ≈ 8 * 3.1416 ≈ 25.1327 feet■
circumference = 2πr = 2π x 6 = 12π units
(circumference=2πr or πd) so the circumference in exact form would be π726.4
the exact circumference is 11pi inches
Circumference of the circle: 7.4*pi cm
The circumference is 62.8318531 inches.
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
31x3.1416=circumference
Circumference = 34*pi miles
find the radius of a circle with circumference of 42.1
Yes, you could if you knew the exact value for pi as well as the diameter of the circle. Multiply the diameter by the exact value for pi to get the circumference. However, it is impossible because the exact value for pi is not known. It is only known to about a trillion decimal places, but the exact value is not known.
The circumference of a circle is the length of the circle's perimeter.
