Question

You just measured a metal cylinder and obtained the following information: mass - 3.543 g diameter -0.53 cm height = 4.40 cm. 265 • Determine the volume (V). (V=nrºh, where r = radius, h = height, T - 3.14) V= (3.14 36205² 4.402.17cm? • Determine density of the cylinder D. 3. SMS-365923 197

Answer 1

Answer:

V cylinder = $\pi r^2 h = \pi(0.53 cm/2)^24.4cm= 0.97 cm^3$

note that $r=diameter/2$

density = $m/V= 3.543/0.97= 3.65 g/cm^3$
