Mathspig is in Melbourne, Australia. We’re in Lockdown. AGAIN!
And toilet paper has disappeared off the supermarket shelves. AGAIN.
So today we are doing maths based entirely on toilet paper using information from the Toilet Paper Fun Facts website. Yes! It exists here.

Mathspig grew up on a police station in the small Australian country town of Kyneton, Victoria in the 1960s. Australia has a very strict gun laws today. But such laws didn’t exist in the sixties. My Dad’s .22 rifle rested against our fridge. He pocketed the magazine.
A .22 means a bullet calibre of .22 inches.
My Dad the Sharp Shooter stopped a stolen car with one bullet. This was considered legendary by his fellow cops. He didn’t shoot the tyres. He managed, by accident and possibly even though he was aiming at the tyres, to hit the electrical lead into the car’s distributor cap. Phht! Car go no more. More on my childhood here.

One measure of the accuracy of rifles, riflescopes but also the sharpshooter is the MOA or Minute of Angle. The MOA can also be used to define the target zone (circle).
I cannot show you a triangle with an angle of 1′ because it would have to be 100m long on one side and only 3cm tall.
Needless to say, drawings are NOT to scale.
A sharpshooter can put 5 out of 6 bullets in a target zone drawn at 1′ angle around centre of target at any distance.
As the distance away from the target increases the target zone circle area increases.
A sharp shooter would be considered very skilled if they can shoot within a target zone (circle) of 10.5 inch radius at 1000 yds. Hitting a bull’s eye at this distance is down to luck.
