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.
