Answer: 1526.8 cubic inches
Step-by-step explanation: Volume = base times height.
The base of the cylinder is πr²
We can use a scientific calculator with π, or we can use 3.14 for π. the radius is 9, 9² = 81.
The Area of the base of this cylinder is about 254.46 square feet
Multiply by the height, 6 feet
We get the volume of the cylinder 1526.82 cubic inches.
Round to 1526.8 cubic feet
Answer:

Step-by-step explanation:
Given
Let the three sides be a, b and c
Such that:

Required
Find c such that a, b and c do not form a triangle
To do this, we make use of the following triangle inequality theorem



To get a valid triangle, the above inequalities must be true.
To get an invalid triangle, at least one must not be true.
Substitute: 



The results of the inequality is:
and 
Rewrite as:
and

This means that, the values of c that make a valid triangle are 1 to 9 (inclusive)
Any value outside this range, cannot form a triangle
So, we can say:
, since no options are given
