Your Toilet Paper is Lying to You

Picture this —

Man sitting on toilet
Why is the bathroom rug there? Why is he using a flip phone? Why am I writing this article in the first place?

I looked up “ominous toilet paper” but nothing could top this.
picture of toilet paper laughing maniacally
Pretty happy with my font choice on this one.

I would like to thank the human race for making this thing of beauty.

Look into the depths of the toilet paper, and you will see yourself as you truly are.
overall toilet paper equation
Please keep reading. I know you don’t want to, but please.
  • a = diameter of entire toilet paper
  • b = diameter of inner tube
  • y = 1/amount you are looking for left (so since we are looking for half of the toilet paper used, y is going to be 2)
diagram of toilet paper explaining equation variables
I used y as the variable because the letter itself is a question.
diameter to area equation
“Why not just use radius instead, so you don’t need to divide by two?” You try finding the center point of a toilet paper roll sometime and get back to me about that.
toilet paper area equation
This also is the equation for a donut.
half of toilet paper area equation
I feel like I’m insulting your intelligence with this equation explainer
finding halfway point equation
I feel like it’s Thanksgiving with all this Pi.
simplified finding halfway point equation to isolate the diameter variable
What an obnoxiously large root. What does this equation think it is, a turnip?
percentage equation
What a breath of fresh air
percentage and diameter length equation combined
Just remind yourself that letters can’t hurt you.

Become the toilet paper knight!

Check out the code linked below, it comes with it’s own cool visualizations.

It’s not that I have a lot of free time, it’s just the little I have I use poorly.
