1. Draw this pretty pattern.

2. Write a non-fruitful function drawEquitriangle(someturtle, somesize) which calls drawPoly from the previous question to have its turtle draw a equilateral triangle.

3. Write a function areaOfCircle(r) which returns the area of a circle of radius r. Make sure you use the math module in your solution.

4. Extend your program above. Draw five stars, but between each, pick up the pen, move forward by 350 units, turn right by 144, put the pen down, and draw the next star. You'll get something like this (note that you will need to move to the left before drawing your first star in order to fit everything in the window):

What would it look like if you didn't pick up the pen?
