5/7/2007 Math 2a
1. HOMEWORK Due today: Page 44 #12
2. Warm-Ups Integer operations
3. P46ff Problem 5.1 /5.2 walk through

OBJECTIVE: 1.1.4 Understand the concept of direct proportion.1.2.1 Analyze how a change in a linear dimension affects other linear measurements (perimeter, circumference) and area measurements. 1.2.6 Understand and apply strategies to obtain reasonable estimates of circle measurements, right triangles, and surface area for rectangular prisms. ACTIVITIES/ASSESSMENT: P46ff Problem 5.1 /5.2 walk through. This is the relationship of the volume of a sphere to the volume of a cylinder and the volume of a cone. NOTES: HOMEWORK: Page 50 problem 5.2 follow-up

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
