Answer 1

It's because of two things - You wrote Math.Pi ,which doesn't exist, so it will be null, and null * 2 equals 0 (use Math.PI). The second problem is that you didn't actually fill. Setting the fillStyle doesn't actually fill.

You got two problems. The first is Math.Pi should be Math.PI. And the second problem is that you need to add c.stroke() to your code.
