pi times the diammeter 3.14159 x diameter
Dan's answer:
circumference= pi X diameter.
2pi X Radius=Pi X Radius (x2)
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
The circumference of a circle is the length of the circle's perimeter.
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
circumference of a circle = 2piradiuis or diameter*pi
