SUMMARY

The discussion centers on calculating the density of a cylinder using the formula for volume, V = πr²h, where r is the radius and h is the height. The user inquires about the correct interpretation of the radius squared (r²) and seeks clarification on how to apply the density formula, D = m/V. The example provided includes a volume of 10 liters, a radius of 0.200 meters, and a height of 15 meters, indicating a need for the mass of the fluid to complete the density calculation.

PREREQUISITES
  • Understanding of the formula for the volume of a cylinder (V = πr²h)
  • Knowledge of the density formula (D = m/V)
  • Basic familiarity with units of measurement, specifically liters and meters
  • Ability to perform calculations involving area and volume
NEXT STEPS
  • Review the calculation of volume for different geometric shapes, focusing on cylinders
  • Study the relationship between mass, volume, and density in fluid mechanics
  • Explore unit conversions between liters and cubic meters
  • Practice solving density problems with varying dimensions and mass values
USEFUL FOR

High school students studying physics or chemistry, educators teaching density and volume concepts, and anyone needing a refresher on geometric calculations involving cylinders.

Im a senior high school now and I am so happy. I miss junior days esp. chemistry.
My problem right now is..hmm.. i forgot how to get the density of the cylinder

V=2\pir2h
thats the formula of the cylinder right?
and I am confuse..
r2=0.200m ->do i have to multiply it 2 times?

thanks you peeps :)

The volume of a cylinder is V=\pi r^2 h, where r2 means r\times r.
 
Copy!

For example
V= 10L
r2=0.200m
h=15
=3.14

And the answer is? formula of the density is D=m/v right? how to get it?

Well, you could do with knowing the mass of the fluid in the cylinder (I'm just guessing that this is a cylinder with fluid in, mainly due to the L)

It would help if you wrote down the question exactly as worded in your textbook, or wherever it's coming from, to save me from having to guess!
