- (General math) The volume of oil stored in an underground 200-foot deep cylindrical tank is determined by measuring the distance from the top of the tank to the surface of the oil. Knowing this distance and the radius of the tank, the volume of oil in the tank can be determined by using this formula: volume=radius2(200distance) Using this information, write, compile, and run a C++ program that accepts the radius and distance measurements, calculates the volume of oil in the tank, and displays the two input values and the calculated volume. Verify the results of your program by doing a hand calculation using the following test data: radius=10feetanddistance=12feet.arrow_forward(Physics) a. Design, write, compile, and run a C++ program to calculate the elapsed time it takes to make a 183.67-mile trip. This is the formula for computing elapsed time: elapsedtime=totaldistance/averagespeed The average speed during the trip is 58 mph. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the elapsed time it takes to make a 372-mile trip at an average speed of 67 mph.arrow_forward(General math) a. Write a C++ program to calculate and display the value of the slope of the line connecting two points with the coordinates (3,7) and (8,12). Use the fact that the slope between two points with the coordinates (x1,y1)and(x2,y2)is(y2y1)/(x2x1). b. How do you know the result your program produced is correct? c. After verifying the output your program produces, modify it to determine the slope of the line connecting the points (2,10) and (12,6). d. What do you think will happen if you use the points (2,3) and (2,4), which results in a division by zero? How do you think this situation can be handled? e. If your program doesn’t already do so, change its output to this: The value of the slope is xxx.xx The xxx.xx denotes placing the calculated value in a field wide enough for three places to the left of the decimal point and two places to the right of it.arrow_forward
- (Physics) a. The weight of an object on Earth is a measurement of the downward force onth e object caused by Earth’s gravity. The formula for this force is determined by using Newton’s Second Law: F=MAeFistheobjectsweight.Mistheobjectsmass.AeistheaccelerationcausedbyEarthsgravity( 32.2ft/se c 2 =9.82m/ s 2 ). Given this information, design, write, compile, and run a C++ program to calculate the weight in lbf of a person having a mass of 4 lbm. Verify the result produced by your program with a hand calculation. b. After verifying that your program is working correctly, use it to determine the weight, on Earth, of a person having a mass of 3.2 lbm.arrow_forward(General math) If a 20-foot ladder is placed on the side of a building at an 85-degree angle, as shown in Figure 3.11, the height at which the ladder touches the building can be calculated as height=20sin85. Calculate this height by hand, and then write, compile, and run a C++ program that determines and displays the value of the height. After verifying that your program works correctly, use it to determine the height of a 25-foot ladder placed at an angle of 85 degrees.arrow_forward(Practice) State whether the following variable names are valid.

- (Electrical eng.) a. Write, compile, and run a C++ program that calculates and displays the value of the current flowing through an RC circuit (see Figure 3.19). The circuit consists of a battery connected in a series to a switch, a resistor, and a capacitor. When the switch is closed, the current, i, flowing through the circuit is given by this formula: i=(EIR)et/RC Eisthevoltageofthebatteryinvolts.Risthevalueoftheresistorinohms.Cisthevalueofthecapacitorinfarads.tisthetimeinsecondsaftertheswitchisclosed.eisEulersnumber,whichis2.71828( roundedtofivedecimalplaces). Using this formula, write, compile, and run a C++ program to determine the voltage across the capacitor shown in Figure 3.19 when t is 0.31 seconds. (Note: The value of RC is referred to as the system’s time constant.) The program should prompt the user to enter appropriate values and use input statements to accept the data. In constructing the prompts, use statements such as “Enter the voltage of the battery.” Verify your program’s operation by calculating by hand the current for the following test data: Testdataset1:Voltage=20volts,R=10ohms,RC=0.044,t=0.023secondsTestdataset2:Voltage=35volts,R=10ohms,RC=0.16,t=0.067seconds b. Check the value computed by your program by hand. After verifying that your program is working correctly, use it to complete the following chart:arrow_forward(Practice) Run Program 7.10 to determine the average and standard deviation of the following list of 15 grades: 68, 72, 78, 69, 85, 98, 95, 75, 77, 82, 84, 91, 89, 65, and 74.arrow_forwardProblem 1.
