6. Some measurements require a different type of measuring device. Use the micrometer to measure the diameter of the wire (and a ruler to measure the length). What kind of geometric "figure" is the wire? Cylinder Diameter 1 = 0.80cm Length 1 = 11.0cm Diameter 2 = 0.079cm Length 2 11.1cm Diameter 3 = 0.078cm Length 3 = 10.9cm Average Length Average Diameter cm www cm To how many decimal places (in cm) can you accurately read the micrometer? Area = m2 Volume = Area Calculation (include formula and units) Volume Calculation (include formula and units)

Part II. Significant Figures The significant figures in a number are all figures that are obtained from the measuring process and exclude those zeros that are included solely for the purpose of locating the decimal point. This definition will be clarified with a number of examples. Number 123 12.3 2016 2.016 2.016 X 10³ 2.01 X 10¹ 2.0 X 10³ 2 X 10³ 10³ 410 410. 4.1 X 10² 4.10 X 10² 41.0 .00159 1.59 X 10 3 0.2 Significant Figures Comments

It's showing that b is not correct. Thank you for your help with this practice problem.
