Vaughn is calculating the volume of the cylinder below using the following work

What was Vaughn’s first error?

He confused the height and the diameter.
He squared 12 instead of 24.
He applied the exponent before multiplying 12 and 5.
He used the wrong units in his final answer.

He confused the height and the diameter

Step-by-step explanation:

the formula should have looked like this

V= 3.14 (2.5)^2 (24)

the reason why it is 2.5 and not 5 is because 5 is the diameter so divide 5 by 2 and you get 2.5

V= 3.14 (6.25) (24)

V= 3.14 (150)

V= 471

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
