1. Page 49 Problem 5.2

OBJECTIVE: See 4-13 above. ACTIVITIES/ASSESSMENT: 1. Page 49 Problem 5.2 NOTES: This unit is a lab showing the relationship of a cone to a cylinder. Distribute the formulas to the students for problem solving purposes.Homework: None

Find the volume of a Cone, Sphere or Cylinder:
picture Enter the radius : 

Enter the height :  		The height dimension is not used on a SPHERE.
The formulas used are:
Cone -   V= 1 / 3 πr 2 h
Sphere -   V= 4 / 3 πr 3
Cylinder -  V=πr 2 h
