Answer:
c. let v = silo.volume();
Explanation:
When you create and initialize a new object you pass through that object's class constructor. The constructor is in charge of initializing all the necessary variables for that class including radius and height. Once you save the object in a specific variable (silo) you need to call the class methods through that variable, using the '.' command. Therefore, in this scenario, in order to call the volume() method you would need to call it from the silo object and save it to the v variable, using the following statement.
let v = silo.volume();
Answer:
The operation that will occur first is D5*C6 (multiplication).
Explanation:
Excel’s default order of operator precedence mandates that Excel perform multiplication before addition and substraction. If you want the addition or substraction to be performed before multiplication or division, they must be in parentheses.
The order of operations in exel is:
1. Evaluate items in parentheses.
2. Evaluate ranges (:).
3. Evaluate intersections (spaces).
4. Evaluate unions (,).
5. Perform negation (-).
6. Convert percentages (%).
7. Perform exponentiation (^).
8. Perform multiplication (*) and division (/), which are of equal precedence.
9. Perform addition (+) and subtraction (-), which are of equal precedence.
10. Evaluate text operators (&).
11. Perform comparisons (=, <>, <=, >=).
