VB Basic Mathematical Calculation

Hello, I need some help on my assignment (I attached the actual assignment at the end of the answers). I did most of the parts but I still have problems writing some codes in Visual Basic. I need answers to the followings: 1. I need a code (Visual Basic) for the syntax X = P * R^2 (P=3.14) 2. I need a code to make the Text boxes, when used to display results, to be read-only. 3. I need a code to create an Exit button. 4. I need a code to Make sure the application accepts and calculates decimal values. Real Assignment: Your employer has requested the development of a software application to calculate the area of a circle. The application must accept only one value (i.e., the radiu... click for more

Visual Basic Advanced Calculations

I have been hired by an engineering company to develop software to perform advanced geometric calculation. My new boss asked me to develop an application that allows engineers to calculate the surface area and the volume of a sphere using Visual Basic. For this, I will need to use the following formulas. Surface Area p = 4r2 Volume = 4/3 p r3 Remember p is equal to 3.14. 1. Allow the user to enter one value in the application (i.e., the radius value). 2. Use NumericUpdown controls to allow the user to enter the values. 3. Display the result in a text box and set it as read-only. 4. Make the Calculate button the Accept button. 5. Create a Clear button to clear the result te... click for more

Visual Basic Math Functions

Develop a simple scientific calculator that will allow the following functions to be calculated using Visual Basic: a) tangent b) square c) sine d) cosine e) absolute value 1. Make the Calculate button the Accept button. 2. Create a Clear button to clear the result text box and reset all controls. 3. Create an Exit button. 4. Use labels to identify the input and output controls.

How many cells can be in a computer's main memory if each cell's address can be represented by two hexadecimal digits? What if four hexadecimal digits are used? Explain your answer.

Write an algorithm, using pseudo code, to perform the following task: Given a string of numbers, identify all of the substrings that form numbers that are divisible by 3. For example, applying the algorithm on the string 37540 should produce the following substrings (not necessarily in this order): 0; 3; 75; 54; 375; 540

At most, two prospectors can travel together and any prospector in the shaft must be with the lantern. The prospectors, named Andrews, Blake, Johnson, and Kelly, can walk through the shaft in one minute, two minutes, four minutes, and eight minutes, respectively. When two walk together ... click for more
