**Proposed exercise**

"sin" and "cos" expect the angle to be measured in radians, instead of degrees. To convert from one unit to the other, you must remember that 360 degrees = 2 PI radians (or 180 degrees = PI radians): float radians = (angle * Math.PI / 180.0);

You might draw 72 points (as there are 360 degrees in a circumference, they would be spaced 5 degreees from each other)

Hint: in C#, cosine is Math.Cos, sine is Math.Sin and PI is Math.PI

**Output**

**Solution**

using System; public class Circunference { public static void Main () { double r, x, y; for(int i = 0; i < 360; i+=5) { rad = i * Math.PI / 180.0; x = 35 + 8 * Math.Cos(rad); y = 10 + 8 * Math.Sin(rad); Console.SetCursorPosition( (int) x, (int) y); Console.Write("X"); } Console.SetCursorPosition(1, 20); } }
