EDIT: To find the diameter, using the circumference - you divide the circumference by the value of Pi - Snakester1962 (Supervisor)
Diameter = Circumference/pi
Diameter = circumference/pi
Circumference = 2*pi*radius
The robber was chased around the buildings' circumference.
Circumference of a circle = 2*pi*radius
Circumference = 2*pi*radius So the radius = circumference/2*pi
Divide the circumference by pi, and that will give you the diameter.
Pi, or 3.14159... Using the equation Circumference = pi * diameter.
Divide the circumference by Pi.
If: circumference = pi*diameter Then: pi = circumference/diameter
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
