Measurement, Uncertainty, Significant Figures

Problem 1 (III): Calculate the volume of the cylinder shown below if the following dimensions are measured as:

d=(3.92±0.005)cm

and

h=(5.45±0.01)cm

Also, determine both the absolute and percent uncertainty of the calculated volume.

(For full credit, fill in the table shown on the top of the next page and show sample calculations.)

quantity value Abs. unc. Rel. unc.

h

V=πr^2 h

Problem 2 (III) Repeat problem 1, but instead of the volume, find the total surface area for the measured cylinder. Find the absolute and percent uncertainty for the calculated surface area. (Again, for full credit, fill in the table below and show sample calculations).

Problem 3 (II) How many nanoseconds are there in one “microcentury”?

Problem 4 (II) An angstrom (symbol Å) is a unit of length, defined as 〖10〗^(-10) m, which is on the order of the diameter of an atom. a) how many nanometers are in 1.0 angstrom? b) how many angstroms are in a centimeter? c) How far away is York from Kearney in angstroms (the distance is 79 miles and there are roughly 1.6 km in a mile).

Step 1

As you have posted multiple questions, I am attempting the very first question posted by you (Problem 1). Kindly, post the other questions separately.

The absolute and percentage uncertainty can be calculated in volume of the cylinder can be calculated using given steps.
