The volume of a cylinder is found using the formula V = πr^2^h. 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
Bruh i had to do this with 3.141 and without calc too
Yeah it's not hard, but if the instructor just wants to test if you can follow directions and plug extremely simple numbers into an equation without a calculator then this is fine. I'd almost expect this on a test for some trade skill, like some 1-2 year certification you know?
~it~ ~could~ ~still~ ~=3~ ~tho~
I also guess that was the intention. But then, why choose an example involving Pi? There are so many ways to test simple multiplications. Books per student, students per class, classes per school, something like that. Or calculate a simple 3D shape which is not round.
That is probably laziness lol
I remember doing multiplication with decimals using lattice multiplication. It's not hard you just need to know how to move the decimal.
Side note, I remember in precalc in high school the teacher marked a student wrong on a test, for showing his work using lattice, because the teacher didn't understand it. The work was right, he showed his work, teacher just didn't know it so it was wrong. Man I hated that teacher.
You gotta learn that school isn't about being correct. It's about obeying authority.
Yeah and i was a defiant little shit in high school. Always going to the exact limits of all the rules we were given. Some of the school security didn't like me, but the teachers did
