if a rubber band can be stretched to a circular shape that has a radius of 3.4 inches. how many 1.3-mm diameter toothpicks could of fit within it? (1 inch = 25.4 mm)

• Math -

ignoring the grammar mistakes, and noting that since the diameter of the toothpicks is small, we can assume they fill "all" the interior, then we can squeeze

(3.4*25.4)^2/(1.3)^2 = 4413 toothpicks into the band
