السلام عليكم ورحمة الله وبركاته


عندي هوم وورك في البرمجة 202 والتسليم يوم السبت ان شاء الله

بس للاسف ماعرفت كيف يتحل

// الغلط منها محاضرتها كلها كلام فاضي لا يمد للهوم وورك باي صلة :@

ممكن اللي يعررف يفيدني بطريقة وخطوات الحل واكون له من الشاكرين


Problem 2:

The Harris-Benedict equation estimates the number of calories your body needs to maintain your weight if you do no exercise. This is called your basal bolic rate or BMR.

The calories needed for a woman to maintain her weight is:
BMR = 655 + (4.3 * weight in pounds) + (4.7 * height in inches) - (4.7 * age in years)

The calories needed for a man to maintain his weight is:
BMR = 66 + (6.3 * weight in pounds) + (12.9 * height in inches) - (6.8 * age in years)

A typical chocolate bar will contain around 230 calories. Write a program that allows the user to input their weight in pounds, height in inches, and age in years. The program should then output the number of chocolate bars that should be consumed to maintain one’s weight for both a woman and a man of the input weight, height, and age.

Notes:

This project gives the student practice with numerical calculations and simple input/output. For a slightly more challenging problem allow the height to be entered in feet and inches and have the program convert to inches.

1 kg = 2.2046226218487757 pounds
1 m = 39.37007874015748 inches






















Problem 3:

Many private water wells produce only 1 or 2 gallons of water per minute. One way to avoid running out of water with these low-yield wells is to use a holding tank. A family of 4 will use about 250 gallons of water per day. However, there is a “natural” water holding tank in the casing (i.e. the hole) of the well itself. The deeper the well, the more water that will be stored that can be pumped out for household use. But how much water will be available?

Write a program that allows the user to input the radius of the well casing in inches (a typical well will have a 3 inch radius) and the depth of the well in feet (assume water will fill this entire depth, although in practice that will not be true since the static water level will generally be 50 feet or more below the ground surface). The program should output the number of gallons stored in the well casing. For your reference:

The volume of a cylinder is where r is the radius and h is the height.
1 cubic foot = 7.48 gallons of water.

For example, a 300 foot well full of water with a radius of 3 inches for the casing holds about 441 gallons of water -- plenty for a family of 4 and no need to install a separate holding tank.

Notes:

This project gives the student practice with numerical calculations and simple input/output. Introduces problem solving with relatively straightforward conversion of units. Students are likely to encounter data type conversion issues from double to int and vice versa (e.g. radius / 12 will result in 0 if radius is an int).
