Question

Mass density of a copper cylinder with theses measurements:
diameter=1.274cm
Height=4.970 cm
Mass=56.77 g

Answer 1

Answer:

8.96 g/$cm^{3}$

Explanation:

Volume of cylinder = base area (height)

                                = π($0.637^{2}$)(4.970)

                                = 6.3356 $cm^{3}$

Density of cylinder = $\frac{mass}{volume}$

                                = $\frac{56.77}{6.3356}$

                                = 8.96 g/$cm^{3}$
