Question

Please I’m struggling in these questions and I only have one post. Thank you in advance

10 1 2 3 4 5 6 7 8 20 The picture above shows a meterstick. The numbers on it are centimeter marks. What is the precision (in unit of meter) of this meterstick?

Answer 1

1) the precision from the diagram is 0.1 m

2) actual diameter = 6.355 - 0.004 = 6.351 mm

3 volume of rod = pi/4 * d^2*l

= pi/4 * (0.0053)^2*6.241

= 137.68*10^-6 m^3

= 137.68 cm^3
