Solution:
In 11 - 15 items, we will use the formula 2πr which we will multiply pi and the radius by 2.
11. ) r = 6 mm
12. ) r = 3 cm
13. ) r = 5 dm
14. ) r = 7 ft
15. ) r = 8 mm
In 16 - 20 items we will use the formula πd which we will multiply pi and the diameter.
16. ) d = 20 mm
17. ) d = 15 ft
18. ) d = 16 dm
19. ) d = 24 mm
20. ) d = 50 cm
