If you change the linear dimensions of an object,how does this change the object's surface area and the volume?

Video Guide Spheres and Proportions

0:01 Introduction to Radius Diameter-Area-and Volume, and the relationship of linear measurement and volume.

1:18 If you had two spheres with a ratio of 1:3 what does this ratio look like with area and volume?

2:26 What if the ratio is 2:5 ? What is the linear measure ratio,the

area ratio, and the volume ratio?

3:07 Example 3 What if you are given the area ratio, how do you find the linear measure, and the volume ratio?

3:57 Example 4 What if you are given the volume 1:8.how do you find the linear and area ratio.

4:30 Example 5

5:02 Example 1

A balloon has a radius of 6 inches. Describe what happens to the balloon's surface area if the balloon inflates and the radius changes 12 inches.

5:46 Problem 2 Describe what happens to the same balloon's volume if the radius is doubled.

6:10 Problem 3 A sphere has a radius of 4 inches. What happens to the spheres volume if the radius is halved.

6:12 A sphere has a radius of 8 inches. What happens to the sphere's surface area if the radius is halved?

7:31 Fill in a table that has..

When the radius is doubled,what is the area, and what is the volume.
