Identify variables in expression $11 r + 5 h r + \pi h$ . Select all correct answers: $r$ , $h$ , $\pi$ .

STEP 1

Assumptions
1. We are given the expression $11 r+5 h r+\pi h$ .
2. We need to identify all the variables in the expression.
3. Variables are symbols that represent numbers or values that can change.
4. Constants are numbers that do not change.

STEP 2

Examine the first term of the expression.
The first term is $11 r$ . In this term, $11$ is a coefficient (a constant), and $r$ is a symbol that can represent a number that may vary. Therefore, $r$ is a variable.

STEP 3

Examine the second term of the expression.
The second term is $5 h r$ . In this term, $5$ is a coefficient (a constant), $h$ and $r$ are symbols that can represent numbers that may vary. Therefore, both $h$ and $r$ are variables.

STEP 4

Examine the third term of the expression.
The third term is $\pi h$ . Here, $\pi$ is a mathematical constant (approximately equal to 3.14159) and does not change. However, $h$ is a symbol that can represent a number that may vary. Therefore, $h$ is a variable.

STEP 5

List all the unique variables identified in the expression.
From the terms $11 r$ , $5 h r$ , and $\pi h$ , we have identified the following variables: $r$ and $h$ .

STEP 6

List all the constants identified in the expression.
The constants in the expression are the numbers $11$ and $5$ , as well as the mathematical constant $\pi$ .

STEP 7

Select all correct answers from the given options based on the identified variables and constants.
The correct answers are: - $r$ (variable) - $\pi$ (constant) - $h$ (variable)
The numbers $11$ and $5$ are constants, not variables, so they are not selected.
The variables in the expression $11 r+5 h r+\pi h$ are $r$ and $h$ .
