Circumfrance

In class we learned about circumference. We learned that circumference is the distance around a circular object. We learned the formula to find the circumference even if you only have the diameter. The formula to do this is ∏ (3.14) multiplied by the diameter.For example lets say that the diameter of a coffee can is 5in. around.

3.14

x 5

15.70

Diameter & Radius

We also learned in class that the diameter is the distance between both sides fo a circle. Also the radius is half of the diameter.

For Example:

If the radius is 6 then then the diameter is 12 because 6x2=12.

    You have just learned about circumfrance,the distance around a circle. Diameter, The distance between both sides of a circle. Also radius, half of the diameter.
