11. (0.7in/yr)*(ft/12in)*19yr = 1.11 ft = 33.8 cm

12. (0.7in/yr)*(ft/12in)*82yr = 4.78 ft = 146 cm

13. (0.7in/yr)*(ft/12in)*527yr = 30.7 ft = 937 cm

Step-by-step explanation:

11. (0.7in/yr)*(ft/12in)*19yr = 1.11 ft = 33.8 cm

12. (0.7in/yr)*(ft/12in)*82yr = 4.78 ft = 146 cm

13. (0.7in/yr)*(ft/12in)*527yr = 30.7 ft = 937 cm
