Answer to Question #136579 in Physics for Dreennn

Question

FA2: A metal cylinder has a mass of 100.0 grams. If it measures 4.0 in high and 1.50 in wide, what is its density (ρ) in g/cm3 if 1.0 in=2.54 cm?

Answer 1

$4.0in=10.16cm$

$1.50in=3.81cm$

$V=\frac{\pi d^2}{4}h=\frac{3.14\cdot 3.81^2}{4}\cdot10.16\approx116(cm^3)$

$\rho=m/V=100.0/116=0.862(g/cm^3)$
