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.

What is the circumference of a circle with the radius of 43?
Circumference = 2pi*r Circumference = 86pi
What is the circumference of 7.8cm?
circumference = 24.5
Circumference in a sentence?
circumference of the tire.
If circle circumference is 12 what is the radius?
Circumference = 12Diameter = Circumference/piRadius = Diameter/2 = circumference/(2 pi) = 1.9099 (rounded)
How do you find a radius if you have the circumference?
You divide circumference / (2 x pi).You divide circumference / (2 x pi).You divide circumference / (2 x pi).You divide circumference / (2 x pi).
