9. 2 m Volume of a Cylinder 6 m Formula: V = Bh or C = πr2h 5 m Examples: Calculate the Volume. ex.1) ex.2) C = πr2h C = πr2h V= π22•5 V= π32•10 V= π22•5 V= π32•10 V= π•4•5 V= π•9•10 V= 20π m3 V= 90π m3 V≈ 62.83 m3 V ≈ 282.74 m3 d 10 m h r d = Diameter r = Radius h = Height h B = Area of the base.

20. 10 in. 24 in. 15 in. 30 in.

21. 10 in. 24 in. 15 in. 30 in. V= πr2h V= 102(15) V = 1500 π V ≈ 4710 in3

22. 10 in. 24 in. 15 in. 30 in. V= πr2h V= πr2h V= 122(30) V = 144• 30π V = 4320 π V ≈ 13564.8 in3 V= 102(15) V = 1500 π V ≈ 4710 in3

24. V= πr2h 35.325= πr2(5) 5 5 7.065 = πr2 π π √2.25 = √r2 1.5 ≈ r

25. V= πr2h 35.325= πr2(5) 5 5 7.065 = πr2 π π √2.25 = √r2 1.5 ≈ r V= πr2h 200.96= πr2(4) 4 4 50.24 = πr2 π π √16 = √r2 4 ≈ r

27. V= πr2h 366= πr2(14) 14 14 336 = πr2 ππ √8.23 = √r2 28.8 ≈ r d= 5

28. V= πr2h 366= πr2(14) 14 14 336 = πr2 ππ √8.23 = √r2 28.8 ≈ r d= 5 V= πr2h 2411.52= πr2(36) 36 36 66.989 = πr2 ππ √21.33 = √r2 4.618 ≈ r d= 9.23
