Step-by-step explanation:
Look at the component form of each vector.
Note that vector c is <4,4> and vector d is <-2,-2>
If one imagined the line that contained each vector, the line for both would have a slope of 1, because 
Since they have the same slope they are parallel, but since they are in opposite directions, we often call them "anti-parallel" (simply meaning parallel, but in opposite directions).
If two vectors are parallel, one vector can be multiplied by a scalar to result in the other vector. This means that there is some number "k", such that
, or equivalently,
and
.
If
and
, we just need to substitute known values and solve for k:

Double checking that k works for the y-coordinates as well:

So, 
The difference between the volume of the spheres is 3428.88 cubic feet
Explanation:
Given that one sphere has a radius of 11 feet.
A second sphere has a radius of 8 feet.
<u>Volume of the 1st sphere:</u>
The formula to determine the volume of the sphere is given by

Volume of the 1st sphere is given by




The volume of the 1st sphere is 5572.45 cubic feet.
<u>Volume of the 2nd sphere:</u>
Volume of the 2nd sphere is given by




The volume of the 2nd sphere is 2143.57 cubic feet.
<u>Difference between the volume of the two spheres:</u>
Difference = Volume of the 1st sphere - Volume of the 2nd sphere
= 5572.45 - 2143.57
Difference = 3428.88 cubic feet.
Hence, the difference between the volume of the spheres is 3428.88 cubic feet.
