Product Description

Sphere Volume Changes

TEKS 8.10b Describe the resulting effects on volume when the dimensions of a solid are changed proportionally.Your task is to:

Record the length of the radius of the sphere shown in each problem on

your answer document.

Calculate the volume of the sphere given and record on your answer

document.

Record the new increased or decreased radius on your answer document.

Calculate the new volume of the sphere after the increase or decrease and

record on your answer document.

Find the ratio of the two volumes by dividing the volume of the new sphere

by the volume of the original sphere. (ROUND TO THE NEAREST WHOLE

NUMBER!!)

For Number 3, your answer will be a decimal convert this to fraction.

There is a relationship between the volume of the original sphere, the scale

factor applied and the volume of the new sphere. Try to see if you can

figure out what that relationship is; answer the questions at the end of the

answer document.

Sphere 1.

A. The length of the radius of the sphere shown is 5 inches. Record on the

answer document. Calculate the volume and record.

B. Double the length of the radius of the sphere and record the new radius on

your answer document. Calculate the volume and record.
