The one that makes most sense would be B since a report is based upon returned data
Computer input devices are :
- mouse (i hope u know how it works)
- keyboard
- joystick (a switch for keyboard for playing games)
- scanners.
- digital cameras.
Answer:
1. #include <iostream>
2. #include <cmath>
3.
4. using namespace std;
5.
6. int main()
7. {
8. float radius;
9. cout << "Type the radius of the base: "; // Type a number
10. cin >> radius ; // Get user input from the keyboard
11.
12. float height;
13. cout << "Type the height: "; // Type a number and press enter
14. cin >> height; // Get user input from the keyboard
15.
16. float volumeCylinder = 3.1416 * radius * radius * height;
17. float cubeSide = std::pow(volumeCylinder, 1/3.);
18. cout<<"Cube side is: "<< cubeSide;
19.
20. return cubeSide;
21. }
Explanation:
- From line 1 to 5 we include two libraries
- From line 6 to 7 we declare our main function
- From line 8 to 11 we ask the user for the radius of the cylinder
- From line 12 to 15 we ask the user for the height of the cylinder
- On line 16 we calculate the volume of the cylinder using the formula V=pi*(r^2)*h
- On line 17 we calculate the side of the cube with the same volume as the cylindrical container using the formula side=∛(V)
- From line 18 to 21 we print and return the value of the cube's side
Answer:
The answer is "Option a".
Explanation:
The ArrayList is often similar to an array but in this, we can re-sized the collection of the elements, that's why it also is known as a dynamic array. As compare to the array, in the array list we increase and decrease the length to fit the new components. It also uses an array to hold the elements. Just like arrays, the index enables users to access their items, and wrong choices can be described as follows:
- In option b, It is wrong because it stores all types of data.
- In option c, It uses the size to described its range that's why it is wrong.
- In option d, It is wrong because It uses index value to represent ArrayList.
Answer:
Jack should check the network connection and check whether it is crashed. The spreadsheet is a work base that can be shared by many users so Jack should also see that he is authenticated to use that spreadsheet or not.
