Circumference is equal to 2 times pi times the radius.
The radius is half the diameter, so pi times the diameter is also the circumference.
In this case, the diameter is 3 meters so 3 times pi equals 9.42
So the circumference is about 9.42 meters.

The circumference of a circle with a diameter of 3 meters is: 9.42 meters (diameter x Pi = circumference).
The diameter of a circle with a 3-meter circumference is: 0.9549 meters.
Circumference of a circle = 2*pi*radius or diameter*pi Its diameter = circumference/pi
It is: 12*pi = 37.699 meters to 3 decimal places
1) First, Measure the Diameter. The diameter is the distance across a circle. It can be be seen as cutting a circle in half. 2) When the diameter is too large to determine, estimate the radius. The radius can be seen as half of the diameter. Once you picture the radius, multiply it by 2. 3) Now you may find the Circumference. Once you find the Diameter of a circle, you multiply it by pi. Pi is the value of 3.14 . Once you multiply the Diameter by pi, you find the Circumference! For example, if a jogger estimated diameter of a circular path as 200 meters across, then circumference would be 200 times 3.14 . 4) Make sure to verify your units of measurement. If your Diameter is in meters, your circumference must be in meters also. You just found the Circumference of a circle!!!
