10. Find the mass density of a ball with 22.0 g and a radius of 0.875 cm.

Ede4ka [16]

Answer:

Mass (m) = 22.0 g

Radius (r) = 0.875 cm

Density (d) = ?

First find ( volume) ;

$v = \frac{4}{3} \pi \: {r}^{3} \\ \\ v = \frac{4}{3} \times 3.14 \times ( {0.875)}^{3} \\ \\ v = \frac{4}{3} \times 3.14 \times 0.66992187 \: {cm}^{3} \\ \\ v = 2.8 \: {cm}^{3}$

$Density = \frac{mass}{volume} \\ \\ d = \frac{m}{v} \\ \\ d = \frac{22}{2.8} \\ \\ d = 7.857 \: \frac{g}{ {cm}^{3} }$
