PRE-LAB Questions:
1) You want to find the volume of a metal sphere (Note: the formula for the volume of a sphere is V = 4/3 pi r^2 , where r is the radius of the sphere). You nmeasure the radius of the sphere to be r = 2.18 cm, with a measurement uncertainty of± 0.02 cm, what is the volume of the sphere as well as the corresponding uncertainty of the calculated volume?
2) You measure the mass of the same sphere used in question 1, and find that its mass is m = 122.2 g, with a measurement uncertainty of± 0.1 g. What is the density of the sphere as well as the corresponding uncertainty of the calculated density?
