<P>Oh yeah, "π, times the radius squared" is the accurate and clearer way to write out a formula. I made that change now. </P>
<P><BR />
Still can't believe I had to write that formula out in the first place, but whatever! </P>Wed, 07 Jul 2021 21:34:01 GMTSajeev2021-07-07T21:34:01ZPiston Slap: Pi are square in the Studebaker's engine displacement | Hagerty Media

"which is π times the radius, squared"<BR />The comma in your expression of the formula implies the wrong calculation IMHO .<BR />The formula is "pi times R to the second power" which is executed as: pi times (radius squared). You have to square the radius before multiplying by pi.<BR />Your original statement gives the impression of: "(pi times radius), squared" which gives a vastly different and incorrect answer. Perhaps to be more clear express as: "π, times the radius squared"<BR />CheersWed, 07 Jul 2021 21:19:02 GMThttps://community.hagerty.com/t5/hagerty-articles/piston-slap-pi-are-square-in-the-studebaker-s-engine/m-p/86145#M47124NightRanger2021-07-07T21:19:02ZRe: Piston Slap: Pi are square in the Studebaker's engine displacement | Hagerty Media

Also reminds me of the scene from the Beverly Hillbillies, when Jethro is explaining to Uncle Jed what he learned in school that day:<BR />Jethro: "I learned pi R squared"<BR />Uncle Jed: "Pies ain't square boy, They's round.
