A quarter of width times height divided by the inverse of pi

πr^2?

engineers use d²π/4 as you can't measure the radius of a pipe or a similar 3d solid object only diameter.

Why would i calculate r? I need only the area. See? Why would I waste my time for an extra calculation.

Life is too short to waste for such things.

You just imported a point cloud, so you can't snap to the centerline, you can only measure the diameter.

This actually explains some of the formulas in research papers I've read.

No its actually r^2π

RandomVideos@programming.dev · 1 pts · 1y

No, its r^π √2

As a side note, I'm taking a refresher math course and ChatGPT is fucking awful at math. Which is pretty weird because I was told it was the best use case scenario for it?

Definitely see why programners aren't really worried about it taking their jerbs

Interesting, what kind of math? I find chatGPT is excellent at analysis and probability theory, less so in algebra, but still serviceable.

DragonTypeWyvern@midwest.social · 3 pts · 1y

Calculus, so, yeah, more or less algebra with depression.

Just make equations into songs. I still remember the quadratic formula and I haven't done any algebra in ten years.

I surprised myself at remembering this one. Possibly the mnemonic of a tasty square pie helped me remember all these years.
