Question
How do you do 7) and 8?
6. Write a non-fruitful function draw_equitriangle(t, sz) which calls draw_poly from the previous
question to have its turtle draw a equilateral triangle.
K (7.)Write a fruitful function sum to(n) that returns the sum of all integer numbers up to and
including n. So sum to(10) would be 1+2+3...+10 which would return the value 55.
8.)Write a function area_of_circle(r) which returns the area of a circle of radius r.
9. Write a non-fruitful function to draw a star, where the length of each side is 100 units. (Hint:
You should turn the turtle by 144 degrees at each point.)
10. Extend your program above. Draw five stars, but between each, pick up the pen, move forwar
by 350 units, turn right by 144, put the pen down, and draw the next star. You'll get someth
