Round #1008

Compute the volume of a cylinder with radius 3 and height 10.

```csharp using System; class Program { static void Main() { // Define the radius and height of the cylinder double radius = 3; double height = 10; // Compute the volume of the cylinder double volume = Math.PI * Math.Pow(radius, 2) * height; Console.WriteLine("The volume of the cylinder is: " + volume); } } ```

```csharp using System; public class VolumeCalculator { public static double CalculateCylinderVolume(double radius, double height) { if (radius < 0 || height < 0) { throw new ArgumentException("Radius and height must be non-negative."); } return Math.PI * Math.Pow(radius, 2) * height; } public static void Main(string[] args) { double radius = 3; double height = 10; double volume = CalculateCylinderVolume(radius, height); Console.WriteLine($"The volume of the cylinder is: {volume}"); } } ``` This C# code defines a method `CalculateCylinderVolume` to compute the volume of a cylinder given its radius and height, using the formula `V_cylinder = πr²h`. The `Main` method demonstrates how to use this method with a radius of 3 and a height of 10.
