Question

formulas for the area of a circle and the volume of a cylinder

Answer 1

the area of a circle is:\[\int_{0}^{x}2\pi r\ dr\]

Answer 2

the volume of the cylindar would take a double integral tho ;)

Answer 3

hahahahahaha, i seriously cant stop laughing right now.

Answer 4

why napervillian??

Answer 5

because he is right.

Answer 6

the rote formulas you get from these are: pi r^2 and (pi r^2)*height :)

Answer 7

\[\int_{0}^{y} \int_{0}^{x}2\pi r\ drdh\]maybe ;)

Answer 8

\[\lim_{n \rightarrow \infty} \sum_{i=1}^{n}2pir _{i}\Delta r _{i}\]

Answer 9

or something like that
