Instructions

This program draws circles of various sizes along with their diameters. It tracks circumference and diameter distances travelled while drawing (which is why looks a bit jittery - the Flash version Scratch 2.0 was MUCH faster and smoother). Then it calculates π by dividing the circumference by the diameter. The cumulative mean of all c:d ratios calculated is displayed.

Description

Mathland Project Ideas & Questions: 1. Why does the mean value of π never seem to equal the the 'expected' value of 3.141593... 2. Remix to generate the value of π with greater accuracy. 3. Remix to use another method of calculating the diameter. 4. Write a new program to draw circles of various diameters, radii, and circumferences without using the turn motion block. 5. Are there other constant ratios for other regular polygons and their diagonals? (e.g., square, hexagon)
