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

Scaling project

OBJECTIVE: See 5-25 above. ACTIVITIES/ASSESSMENT: Students will create a net for a prism and a cylinder. They will calculate the volume and surface area of each. They will apply the idea of scale factor (of their own choosing) to each figure and calculate the volume and surfce area of their scaled objects. NOTES: Provide data sheet and calculation guides. Will also benefit from a software corrector scheme... HOMEWORK: None - Continue this project.

Scaled Containers Project

OBJECTIVE: " To apply strategies for finding the volumes of rectangular prisms to designing boxes with given specifications " To investigate the effects of varying the dimensions of rectangular prisms on volume and surface area and vice versa. ACTIVITIES/ASSESSMENT: Students will create a net for a prism and a cylinder. They will calculate the volume and surface area of each. They will apply the idea of scale factor (of their own choosing) to each figure and calculate the volume and surfce area of their scaled objects. NOTES: HOMEWORK: Project due 6-2-2005

HOMEWORK: Scaled Containers Project
Page 69, Problem 7.1

OBJECTIVE: " To estimate the volume of an irregular shaped object by measuring the amount of water it displaces " To understand the relationship between a cubic centimeter and a milliliter. ACTIVITIES/ASSESSMENT: Page 69, Problem 7.1 - finding volume through displacement. NOTES: HOMEWORK: 1 cup = 240 ml(approx) Using the conversion factor, measure an irregular object around your house.
