Volume of Prism and Cylinder

Volume of Prism and Cylinder. Brittany Henderson, Kristy Lee, Allen Long. Cylinder. 3- dimensional figure two similar bases The volume of a cylinder is the area of the base times the height. Example: d = 4.8=5, h =4.95=5 R = d divided by 2 = 5 divided 2 = 2.5 V = (pie r2)h

  1. Volume of Prism and Cylinder Brittany Henderson, Kristy Lee, Allen Long

  2. Cylinder • 3- dimensional figure two similar bases • The volume of a cylinder is the area of the base times the height. • Example: d = 4.8=5, h =4.95=5 • R = d divided by 2 = 5 divided 2 = 2.5 • V = (pie r2)h =(3.14)(2.5)x5 =(3.14)(6.25)(5) =19.625x5 =98.125=98 The volume of the is approximately 98 m3

  3. Prism Volume (v) of a prism is the area of the base times the height Example: B =2x5 = 10 m2 V= Bh =10x7 =70 m3

  4. Example Volume of Figure = Volume of a rectangular prism + Volume of triangular prism V=(6)(9)(19) + ½ (6)(3)(9) = 1026 + 81 = 1107 cm3

  5. Questions Class 1. Cylinder A has a radius 6 cm and height 14 cm. cylinder B has radius half as long as a cylinder A. What is the volume of a cylinder B? Use 3.14 for pie and round to the nearest tenth. A 393.5 cm3 B 395.6 cm3 C 422.3 cm3 D791.3 cm3

  6. Question 1 • Since Cylinder B is half of cylinder A that make Cylinder B 3 • So you multiply 3.14x3 squaredx14 • 3.14x3squared=28.26x14=395.64 • B

  7. Question Class • 2. A tractor trails has dimensions of 13ft by 53ft • By 8ft.What is the volume of the trailer. • A 424ft3 • B 689ft3 • C 2756ft3 • D 5512ft3

  8. Question 2 • Should be B (area of the base) • Multiply 13ftx53ft=689ft • B

  9. Find the volume of each figure to the nearest tenth.Use 3.14 for pie • 2inx5inx10in • 1.5cm with a radius of 11cm • 6mx13mx9m =

  10. 1. 289 • 2. when you muilply 1.5cmxthe radius of 11cm=51.81cm • 3. 2204.28
