Today, I had to Google how to find the area of a circle. I'm working on my PhD in engineering. FML

A failed costume, stolen candy and a very real scare: Halloween, the one night when fear is allowed.

I'm 15 and I know the area of a circle=pi r2 and the area of a sphere=3/4 pi r3

I think that volume is wrong. Integrating a r^2 which is present in a circle to get the r^3 in volume would give you a 3 in bottom, not the top.

Fuzzy wuzzy was a bear area of a circle equals 3.14r^2

A=PIr2nd

It's 3.14x radius squared because there is 2 radiuses Ina. Diameter

^ don't listen to this guy

yess and there are six radians in a circle im glad we all know our grade school math

Hey, what did the engineer say to the tool maker? "Would you like fries with that?" Point in case once again that 99% of engineers are a waste of space... But congrats, you are NOT the 1%. #occupyfuturemcdonaldsenployee

I'm 14 and I kno :) pi x radius squared !!!

pi (r squared). I leaned that in elementary school

Pi r squared, dumbass!

American education at its finest

Really, you've never forgotten something that you once knew well then?
