The volume of a cylinder is found using the formula V = πr2h. Using π = 5, r = 10 and h = 10. Find the volume V.

Probably a test meant to be done without a calculator.
… at least make it =3
Considering that the r and h are 10, you could still easily do it without calculator, even if the value of pi had plenty of decimals.
You guys are really overestimating the students this test was made for lol
Irrational
Pi is a geometric constant, so obviously we’re redefining the decimal numbering system to make “1” anchored to a fixed value of π/5 (or simply 1 in our superior new decimal representation).
Don’t believe the haters who’ll complain about “needing integer number representations”. Literally anyone with a basic grasp of fractions will be perfectly fine! Let’s illustrate with a few simple examples:
- “I’ll take three-fifths pi gallons of blue slushie, please”
- “No thanks, I don’t need any cups because I actually brought two-fifths pi containers of my own each with three-tenths pi gallons of individual capacity specifically for this purpose”.
As you can see, there is no reason to be concerned whatsoever. The system works. It is mathematically elegant.
Indiana almost passed a law making pi = 3
Must have asked a cosmologist.
