✓ 1.
The number π is the ratio of the
and
of a circle.
✓ 2. One way of estimating the value of π is by randomly dropping needles of length l
on a sheet of paper containing parallel lines that are a distance l apart. The probability of a needle landing on a line is 1/2π, or 0.6366. If 100 needles are randomly dropped, how
many needles would be expected to cross lines?
✓ 3. Press Continue to run the simulation of Buffon's Needle.
✓ 4. In the simulation, %1 needles landed across lines. The value of π can be estimated by dividing 200 by the number of needles that crossed lines in the simulation.
In this example, π = 200 / %1 = %2.
