title: I was writing a menu driven program to find the volume of some shapes. However, there is a problem in the calculation of sphere's volume. Pls help me
body: <p>The formula for volume of a sphere is 4/3 intio 3.14 into radius into radius into radius. In my program I have used this formula only but in the calculation for the volume, the 4/3 is omitted. It only multiplies 3.14 with radius cubed. Here is the code</p>

  <p><a href="https://i.stack.imgur.com/jBsAz.png" rel="nofollow noreferrer">part 2 of the code</a></p>
  <p>In the output, 4/3 is not getting multiplied. Only 3.14 is multiplied with radius cube. Any reason why the multiplication with 4/3 is getting omitted? If so, what is the fix?</p>
