Enjoy a bonus comic. The regular comic will still post on Friday. I got the idea for this when I realized I’d put the wrong formula for a sphere in the previous strip called Existentialism in your Head. Someone finally pointed it out to me. It’s been corrected now.











The cylinder formula is wrong, too.
“The cylinder formula is wrong, too.”
It’s correct for an open cylinder. It doesn’t include surface area for the ends. For a closed cylinder it would be 2(pi)rh + 2(pi)r^2.
It’s never wrong if you use the chicken to measure it!
Actually Dale, if it’s open, you must add the interior surface as well, so it’d be ~4(pi)rh assuming a thickness of ~0.
