About Geometry Worksheet Assignment 10.14:             

 

Assignment 10.14 is an introduction to calculating the circumference of a circle.

 

Prerequisite Skills:  Use the pi symbol       and approximate value for pi (3.14) as the ratio of the circumference to the diameter of a circle (Activity 10A). 

 

Theorems:   The circumference of a circle is equal to the diameter multiplied by pi.   

                            The circumference of a circle is equal to twice the radius of a circle multiplied by pi.

                            The diameter of a circle is equal to the circumference divided by pi.
