SECTION A QUESTION 1: GENERAL PROGRAMMING SKILLS Do the following: Open the incomplete program in the Question1 folder - NSC Information Technology - Question 1 - 2018 - Paper 1

To calculate the volume of the can, follow these steps in the button click event:

1. Declare the necessary variables:

   var
   Radius, Height, Volume: Real;
   

2. Extract the height and radius from user input:

   Radius := StrToFloat(edtRadius.Text);
   Height := StrToFloat(edtHeight.Text) + 1; // Adding space of 1 cm
   

3. Calculate the volume using the formula: $Volume = ext{pi} imes ext{Radius}^2 imes ext{Height}$

   Volume := Pi * Sqr(Radius) * Height;
   

4. Display the volume rounded to one decimal place:

   ShowMessage('The volume of the can is: ' + FloatToStrF(Volume, ffGeneral, 2, 1));
