1. Calculate the radius of an aluminum cylinder given the following data: Mass = -2.050g Height of aluminum = 2.70g/cm 3 V = r 2

1. Calculate the radius of an aluminum cylinder given the following data:

Mass = -2.050g

Height of aluminum = 2.70g/cm ³

V = πr ² h

2. Calculate the radius of an iron ball of mass 5.2241g and density 7.874/cm ³ .

(volume of a sphere V = (4/3)πr ³ )

3. Calculate the mass of lead (11.43g/cm ³ ) that has the same volume as a cylinder of silver(10.49g/cm ³ ) of mass 21.5096g.
