Find Volume, SF & Uncertainty of Iron Sphere

In summary, the formula for finding the volume of a sphere is V = (4/3)πr³, and the surface area can be calculated using the formula SA = 4πr². The uncertainty of the measurements can be determined by considering the precision and accuracy of the measurement tools used and accounting for any sources of error. It is important to calculate the uncertainty to ensure the reliability and accuracy of the results. The volume and surface area of an iron sphere can be measured experimentally using various techniques, but it is crucial to follow proper procedures and account for potential sources of error for accurate measurements.

A copper cylinder has a mass of 56.09g with an uncertainty of +/- 0.01g, how do I find the absolute uncertainty and the relative uncertainty?

An iron sphere has measurements:
Height = 2.3cm +/- 0.05
Diameter = 2.3cm +/- 0.05
Mass = 66.69g +/- 0.01

Find the volume with the correct unit, amount of significant figures and uncertainty
