Let’s Begin…
The team from Numberphile printed one million decimal places of Pi onto a piece of paper which stretched for over a mile. They rolled it out on a runway usually used for testing planes and cars.
The amount of ink used in this video is just 8.16 millilitres and the paper roll weighs 20kg. If the team wants to wrap a new piece of Pi around the Earth's equator (40,075km), how many digits will they now require (assuming the printed numbers stay the same size)? How many GALLONS of ink will be needed? And what will the new paper roll weigh?
