Answer:
The volume is about 4.24 cm^3.
Step-by-step explanation:
From the question we are told that:
Diameter
Radius 
Height risen
Generally the equation for Volume of a Key is mathematically given by
Since Volume of a cylinder is Given as

Therefore


Correct Option A
The volume is about 4.24 cm^3.
The function is computed below based on the information. The answers will be:
1. -11
2. -1
<h3>How to compute the function?</h3>
f(x) = x²-11x+28
g(x) = x-4
(f+g)(-5) = (-5² - 11 × 5 + 28) + (-5 - 4)
= 25 - 55 + 28 - 9
= -11
(f-g)(5)
= = (5² - 11 × 5 + 28) + (5 - 4)
= 25 - 55 + 28 + 1
= -1

Answer:
The following variable is categorical.
Step-by-step explanation:
Consider the provided information.
Categorical variables: It take the values of categories or labels and position an entity in one of more classes.
Quantitative variables: It take numerical values and represent a calculation of some kind.
Now consider the given scenario.
Teenagers with a question that asks ‘‘Do you eat at least five servings a day of fruits and vegetables?"
Here we have two categories i.e fruits and vegetables.
Therefore, the following variable is categorical.
4/12 of the fans are kids because 1/4 can be multaplied by 3 to get 3/12
X=(3^4) * (2^3)
x=(81)*(8)
x= 648
