Significant Figures and Math Operations.
Solve the problem with the correct number of sigfigs.
9. 12 cm + 0.031 cm + 7.969 cm = 20,000 - 2 signigs
10. 3.419 g + 3.912 g + 7.0518 g + 0.0013 g = 14, 3849=5 signags
11.289 g-43.7 g=245.3g=4 sigings
12. 62.47 g-399g=22,69.3 sigrigs
3.08 m 1.2m = 3.7m2=2 sigfigs
14. 109.3758 r m² 5.813 m. = 18.82m=4 sigrigs
15. .5.0 cm X 5.0 cm = 25.0cm= 2 signigs
16.85.621 km2 8.05 km = 21.5 - 3 Sigfigs
