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

OBJECTIVE: •To develop strategies for finding the volume and surface area of a cylinder[1.2.1; 1.2.2] •To compare the process of finding the volumes and surface areas of cylinders and rectangular prisms[1.2.5; 1.2.6] •To investigate interesting problems involving the volumes and surface areas of cylinders and prisms. ACTIVITIES/ASSESSMENT: Page 40 Problem 4.3 all. This will be a presentation model for posting. Requirements are: A juice can and net and the new juice box and net with a comparison of dimensions, surface area and volumes. Prepare on a poster style sheet (teacher provided.) Neatness counts. Due on 5-18. NOTES: HOMEWORK: Calculation quiz practice - no calculators!

Optional Challenge Question: What is the largest volume cylindrical net that can be cut from a single sheet of 8-1/2 by 11 inch paper (volume in cubic inches) and what is the largest surface area cylindrical net that can be cut from a single sheet of 8-1/2 by 11 inch paper (surface area in square inches)?

Requirements: 1) both nets 2) labeled calculations that support your choices 3) narrative on how you reached your choices.

Due May 24 in poster format. MUST be neat and tidy - no visible tape or staples, no tears, no text in illegible colors. 3 credits max.
