Hi
I need PHP functions for calculating the area and volume of a cylinder?
I will be thankfull for your answer.
<form action="functions.php" method="POST">
Enter the radius = <input type="text" name="radius"><br>
Enter the height = <input type="text" name="height"><br>
<input type="submit" name="submit" value="Calculate"><br>
</form>
<?php
//calculates the volume of a cylinder
//Volym = π r2 h
function volumeCylinder($r,$h)
{
$pi = 3.141592653589;
$volume = 2 * pi *radius *(radius + height);
//return volume;
echo "The volume is", volume;
}
?>
