FoxTrot by Bill Amend for November 19, 2023

9.13 × 10^26 pies.

Each pie would have a volume of 1809.56cm^3 (assuming it’s a perfect cylinder) meaning the total mass of each pie is 2080.994 grams. We’ll make it 2.08kg for simplicity and round to hundredths.

Jupiter’s mass is 1.89×10^27kg, so in total it would take 9.09×10^26 pies.

And as for the whipped cream, if we assume 200ml (.2 Liters) of whipped cream per 1/8th of a pie, 1.45×10^28 liters.

If they had a density of 1.15 g/cm3, you’d need a table aprox. 3.14(cm2x2y3) thick

All that pie talk, I’m surprised he didn’t eat the paper.

Pie = 3.14

The calculations are [mostly] correct, as far as they go, but they make an assumption. They assume pies have vertical edges. I call that a cake.

If we instead assume a 45 degree angle on the edge instead, and do the integral, we find the pies lose almost 30% of their mass. I get 1.296×10^27 pies.

As for the bonus: 0. The chef should make no pies and no whip cream. He can’t get enough ingredients to do the job.

FYI: it is integrate pi x^2 dx from 8 to 12; then multiply by 1.15 to get the mass of the pie.

This becomes: ( pi * 12^3 / 3 – pi * 8^3 / 3) * 1.15

Regrouping and subtracting: 1.15 * pi * 1216 / 3 grams/pie = 1464.40 grams/pie(which should probably be rounded to 1460 due to lack of precision on the density, or even 1500 due to lack of precision on the diameter, or even …. .)

That reminds me of a bonus question my astronomy teacher had. If the moon were really made of green cheese with a density of 3.5 g/cm^3, what would its mass be? He gave us some measurements, constants, and formulae.

I averaged over 100% in that class. Fun!

Today’s classic FoxTrot Sunday strip:

That looks like a problem Jason would enjoy.

Mr. Amend is showing off his football fandom.

No way do I believe that. I’ve taught physics for 23 years, and physics teachers are ALWAYS silly.

Gronk’s Jersey! (I also have it in blue).

It figures Paige would be a Swiftie

Is the girl wearing a Travis Kelce jersey? Good grief!!

My algebra teacher in college gave out a “pop” quiz the last day before Christmas break (greeted by a collective groan from the class). Format was solve and write answer in blank in front of the question (for easier grading we thought). When solved correctly the answers read “Merry Christmas”. Yes it was that long ago.

That’s one way to get Peter to pay attention in class.

Paige musr be a Swiftie. Wearing that red #87 shirt.

Physics? More like math.

Nice touch to have Paige sporting the Travis Kelce jersey. Go birds

Yeah, I had a few teachers that were like that and coming up with holiday-themed problems for us the students to solve. Admittedly though, I never really thought too much about it since it still meant I had to solve problem, and usually around the holidays too, no less. :P

Am I the only one noticing (or commenting on) Paige being a Swift-kneecap-sucking Kelce fan?!?

3.1415926

Since there is only one significant digit in the thickness, there should be only one significant digit in the solution; 9 × 10^26 is what the teacher would be looking for.

As for how much whipped cream, since this is Peter we are talking about, the answer is, “As much as the chef can.”

Silly, but practical.

So was the mass of Jupiter just given as a constant earlier in the lesson? Like, as a way to teach students how to use exponents to do math with very large numbers?

Yup, That’s a Travis Kelsey jersey! That dude can catch a football! Good choice!

I used to do stuff like that. (my students loved it… ha!)

Travis Kelce jersey. She must be a Swifty.

Putting math in interesting terms it would seem…..

Make that pecan, and I might try to figure it out.

Too bad more science/math questions weren’t like this…

I remember there was a Sunday Foxtrot strip where Peter used a valid formula to calculate the trajectory of a cannon ball shot from a pirate ship. I showed it to my Physics instructor and he got a kick out of that.

By the jersey it’s clear Paige is a Swifty.

Oddly, this is putting me in mind of Randall Munroe’s fascinatingly disturbing “mole of moles”. >

All these comments and nothing about Paige being a Swiftie?

My physics prof used Batman swinging his Batarang as a problem for calculating centripetal velocity.

I love how Paige is dressed in a Travis Kelce jersey now. I’m sure it has everything to do with her love of the Kansas City Chiefs and nothing to do with Kelce dating Taylor Swift.

Not enough information as the mass of Jupiter is not provided.

Plot twist: Jupiter is a pie giant.

Bonus: If li’l brother eats it, there isn’t enough whipped cream in the universe.

The answer that I got is 5.5158 octillion pies and 243 sextillion short tons of whipped cream.

Pumpkin pie!! As a non American I’ve got to say yuck!!!
