A hollow sphere of inner radius 8.69 cm and outer radius 9.99 cm floats half-submerged in a liquid of density 927.00 kg/m3. (a) What is the mass of the sphere? (b) Calculate the density of the material of which the sphere is made.
Answers: 1
, b) 
![m_{sph} = (927\,\frac{kg}{m^{3}} )\cdot \left[\frac{4}{3}\pi\cdot (0.099\,m)^{3} \right]](/tpl/images/0588/1439/26b05.png)
![\rho_{sph} = \frac{3.768\,kg}{\frac{4}{3}\pi\cdot [(0.099\,m)^{3}-(0.087\,m)^{3}]}](/tpl/images/0588/1439/369d2.png)
