If I want to approximate a circle of a given diameter (D) using planks of a known width (W), then I can work out how many planks I will need (D/W), but is there a way of calculating the length of each plank? The middle plank length equals D, but how much does each subsequent plank reduce by?
Maybe the easiest is to draw a 1/4 circle onto graph paper with a compass and then take readings along the top edge where each plank would start/end and double the distances.

only showing half the planks for brevity
