In general, the volume

has total derivative

If the cylinder's height is kept constant, then

and we have

which is to say,

and

are directly proportional by a factor equivalent to the lateral surface area of the cylinder (

).
Meanwhile, if the cylinder's radius is kept fixed, then

since

. In other words,

and

are directly proportional by a factor of the surface area of the cylinder's circular face (

).
Finally, the general case (

and

not constant), you can see from the total derivative that

is affected by both

and

in combination.
36 and 144
Explanation
Two Angles are Supplementary when they add up to 180 degrees
Step 1
Let
x= angle 1
y= angle2
The measure of one angle is four times the measure of the other angle,then

x and y are supplementary angles , then

Step 2
use Equation (1) and (2) to find x and y

replace Equation (1) in Equation (2)

replace the value of y= 36 in equation (1) to find x

Hence, the answer is 36 and 144
Answer:
divide 150 by 12 ( because there are 12 inches in one foot) and your answer would be 12.5 feet.
