  13. HomeworkAnswers

  14. Goal for today Volume Pyramids

  15. Discovery Can you discover the rule?

  16. Pyramid and Cone v=1/3Bh What does this formula look like?

  17. Important Comparisons A Pyramid is 1/3 the size of a Prism with the same Base. A Coneis 1/3 the size of a Cylinderwith the same Base.

  18. Pyramid and Cone v=1/3Bh B= Base Base depends on what kind of base the shape has: Rectangular Pyramid: l x w Triangular Pyramid: 1/2bh

  19. #1 Find the volume of the pyramid to the nearest tenth. Estimate to check whether the answer is reasonable. 1 3 V = Bh Use the formula. 4 ft Find the area of the rectangular base. B = 5 · 7 = 35 1 3 V = · 35 · 4 Substitute for B and h. 7 ft 5 ft Multiply. V ≈ 46.7 ft3 1 3 V = Round the measurements. · 30 · 5 Estimate The answer is reasonable. V = 50 ft3

  20. 1 3 ·52 ·6 · ≈ 1. V ≈ Find the volume of the cone to the nearest tenth. Use 3 for . Estimate to check whether the answer is reasonable. 1 3 Use the formula. The base is a circle so B = ·r2 3.14 · 52  78.5. Bh V = 1 3 Substitute for B and h. · 78.5 · 6 V  V  157 yd3 Multiply. 1 3 Estimate  150 yd3 The answer is reasonable.
