  • 4. Lesson 7B~ Surface Area: Cylinder22. Find the surface area for the figure below.Lesson 8~ Volume: Rectangular Prism & Triangular Prism23. Find the volume.
  • 5. 24. Find the volume.Lesson 9~ Volume: Cylinder25. Find the volume
  • 6. Name _______________________________ Date ___________________Mrs. Labuski / Mrs. Portsmore Period ______ Chapter 10 Unit Test PracticeLesson 1~ Perimeter1. What is the perimeter of the polygon? x x=2+6+2 102cm 2cm x = 10cm 2 2cm 2cm↑ 2 8cm ←8cm 8 6 6cm 8 2 +2 40cmLesson 2~ Area of Rectangle, Parallelogram, TriangleShow all work: formula, plug in, math, answer, label!!!2. Find the area of the rectangle. A = lw A = 3x6 A = 18cm2 3. Find the area of the parallelogram. A = bh A = 7x6 A = 42cm24. Find the area of the triangle. A = ½bh A = ½ x 15 x 6 A = ½ x 90 A = 45cm2
  • 7. Lesson 3~ Area of Composite Figures5. Find the area of the polygon. All angles in this figure are right angles. Area = lw Area = lw Area = 8 x 10 Area = 6x6 Area = 80 Area = 36 2 Area = 80in + 36 in2 Area = 116 in2Lesson 4~ Comparing Area & Perimeter6. Find how the perimeter and the area of the figure change when its dimensionschange. When the original figure’s length and width multiplies by 4, the perimeter multiplies by 4 and the area multiplies by 42 (16).Lesson 5A~ Circles: Parts & Circumference7. Name the circle G8. Name the two radii of the circle. GH, GK, GJ9. Name the chord of the circle. HK 6cm10. What does the diameter measure? 6cm11. What does the radius measure? 3 cm12. What is the circumference of the circle? C=πd C = 3.14 x 6 C = 18.84 cm
  • 8. Lesson 5b~ Circles: Area, Central Angle, Sector B13. What is the central angle? ∠BAC or ∠CAB14. Color in the sector of the circle. 6cm15. What is the area of the circle? ______________ A C A = πr2 A = 3.14 x 62 A = 3.14 x 36 A = 113.04 cm2Lesson 6~ Solid Figures16. Identify the shape. rectangular pyramid17. Identify the number of faces 518. Identify the number of edges 819. Identify the number of vertices. 520. Is it a polyhedron? Explain. Yes because it is a three-dimensional figure withflat surfaces,Lesson 7A~ Surface Area: Prism & Pyramid21. Find the surface area for the figure below. 4 2 2 2 4 ft 9 ft 3 ft 16ft 9 ft 14 ft 4 ft 14 ft 3 ft 4 ftA = lw A = lw A = lw A = ½bh A= lwA = 14 x 9 A = 3x9 A = 14x3 A = ½ x 4 x 16 A = 4 X 4 2A = 126ft A = 27ft2 A = 42ft2 A = ½ x 64 A = 16 ft2 x2 x2 x2 A = 32ft2 2 2 252ft 54ft 84ft2 x4 A = 252+ 54 + 84 A = 128 ft2 A = 390 ft2 A = 128 + 16
  • 9. A = 144ft2Lesson 7B~ Surface Area: Cylinder22. Find the surface area for the figure below. r = 3m d = 6m 2 C = 18.84 = length 3m 12m A = πr2 C = πd A = 3.14 x 32 C = 3.14 x 6 A = 3.14 x 9 C = 18.84 m A = 28.26 m2 A = bh x2 A = 18.84 x 12 A = 56.52 m2 A = 226.08 m2 S = A of bases + A of curved surface 56.52 m2 +226.08 m2 S = 282.6 m2Lesson 8~ Volume: Rectangular Prism & Triangular Prism23. Find the volume. V = lwh V = 15 x 3 x 8 V = 45 x 8 V = 360 ft3
  • 10. 24. Find the volume. Remember that “B” equals the area of the triangle which is A = ½ bh h = the height of the figure when it is flipped on its base V = Bh V = (½ x 7 x 14) x 21 V = (½ x 98) x 21 V = 49 x 21 V = 1029m3Lesson 9~ Volume: Cylinder25. Find the volume r = 3m V = πr2h d = 6m V = 3.14 x 32 x 12 V = 3.14 x 9 x 12 V = 3.14 x 108 V = 339.12 m3 Formula Formula Plug it Plug it Multiply Multiply It’s that easy It’s that easy Give it a try! Give it a try! It’s not hard It’s not hard Don’t be scared Don’t be confused Just remember Just remember Area’s squared! Volume’s cubed!
