Answer: There are 34.35 liters left in the test tube.
Step-by-step explanation:
Since we have given that
Depth of the tube = 9 inches
Circumference of base=4 inches
As we know the formula of circumference ,

Now, we need to find the volume of tube is given by

Since we have also given that,
Of 1 cubic inch of space holds 3 liters of water,
So,

Hence, there are 34.35 liters left in the test tube.

Step-by-step explanation:
With the two points you find the slope using 
Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
Step-by-step explanation:
p² + q² + 5(p² + q²)
= 1(p² + q²) + 5(p² + q²)
= (1 + 5)(p² + q²)
= 6(p² + q²).
