If you know that the exact volume of a cylinder is 500 π cm3, how can you find the approximate volume, without knowing the height or radius of the cylinder? answer in a full sentence, and then calculate the approximate volume.

i would like to you in advance if i don't get the chance to

Provide an example of a trigonometric function and describe how it is transformed from the standard trigonometric function f(x) = sin x, f(x) = cos x, or f(x) tan x using key features.

Anyone know? is appreciated! will mark brainliest if correct!

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
