The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
diameter = circumference/pi
You cannot find the diameter of something from its circumference unless it is a circle and, in that case, diameter = circumference/pi
circumference = pi x diameter
by timesing the circumference by pie
The length of the curved part of the semicicle is π*d/2 where π is the transcendental number approximated by 3.14159 and d is the diameter. The length of the straight part of the semicircle is, of course, d.
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
Diameter = Circumference/pi
You divide the circumference by pi.
Circumference = π * Diameter
diameter = circumference/pi
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
You cannot find the diameter of something from its circumference unless it is a circle and, in that case, diameter = circumference/pi
Divide the circumference by Pi to find the diameter.
Divide the circumference by PI (3,14159...)
The circumference is: 32.1
