Answer: 
Step-by-step explanation:
Since you indicate that it is a cone, you need to use the formula for calculate the volume of a cone. This is:

Where "r" is the radius and "h" is the height of the cone.
According to the information given in the exercise, the height and the radius of the pylons are the following:

Then, knowing these values, you can substitute them into the formula,as following:

Finally, evaluating, you get that the volume of concrete that Tobias will need for each pylon is the one shown below:

-12 + 9 - (-3) - 11
Remember PEMDAS: This is the order of operation.
P-Paragrahp
E-Exponent
M-Multiply
D-Divide
A-Add
S-Subtract
1st step: PEM
-(-3) is actually -1 * -3 = + 3
-12 + 9 + 3 - 11
2nd step: D is not possible, so we do A.
9 + 3 = 12
3rd Step: Subtract
12 - 12 - 11 = 0 - 11 = -11 CHOICE B.
Answer:
The given value is discrete variable.
Step-by-step explanation:
Discrete Variable:
Discrete Variable are those variables that can only take on a finite number of values are called "discrete variables." All qualitative variables are discrete. Some quantitative variables are discrete, such as performance rated as 1,2,3,4, or 5, or temperature rounded to the nearest degree.
