If the radius of a sphere is reduced to one-third, by how many times does its
volume decrease?

It can be concluded that reducing the radius to one-third will reduce the volume of sphere 1/27 times

Step-by-step explanation:

The volume of a sphere is given by the following formula:

Here r is the radius of the sphere

Reducing the radius of sphere to one-third means dividing the radius by three. So the new radius will be:

The new volume with the new radius will be:

The new volume is 1/27 times of the original volume.

Hence,

It can be concluded that reducing the radius to one-third will reduce the volume of sphere 1/27 times

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
