A sidewalk is to be constructed around a swimming pool that measures (10.0 0.1) m by (17.0 0.1) m. If the sidewalk is to measure (1.00 0.01) m wide by (9.0 0.1) cm thick, what volume of concrete is needed and what is the approximate uncertainty of this volume?
A surveyor measures the distance across a straight river by the following method (Fig. P3.7).

In the following problem I am asked to calculate a volume respecting the rules of significant figures: v=(4/3)pi (R^3)Where R=4.5cmHow should I do the calculation taking into account the significant figures? Should I do the direct calculations and at the end use as the number of significant figures the number that has fewer figures after the decimal point?or parse R separately first? applying the same ruleFirst of all, Thanks.

A block of gold has a length of 5.62 cm. width of 6.35 cm and height of 2.78 cm. (a) Calculate the length times the width and round the answer to the appropriate number of significant figures. (b) Now multiply the rounded result of part (a) by the height and again round, obtaining the volume. (c) Repeat the process, first finding the width limes the height, founding it, and then obtaining the volume by multiplying by the length. (d) Explain why the answers don't agree with the third significant figure.
