Unit Nine: Surface Area and Volume

• 9-1 Objective: The student will be able to determine the area of a variety of shapes including polygons, circles, and sectors of circles.


• 9-2 Objective: SOL G.13: The student will use formulas for surface area and volume of three-dimensional objects to solve real-world problems.


• 9-3 Objective: SOL G.13: The student will use formulas for surface area and volume of three-dimensional objects to solve real-world problems.


• 9-4 Objective: SOL G.13: The student will use formulas for surface area and volume of three-dimensional objects to solve real-world problems.


• 9-5 Objective: SOL G.14: The student will use similar geometric objects in two- or three-dimensions to
  a) compare ratios between side lengths, perimeters, areas, and volumes;
  b) determine how changes in one or more dimensions of an object affect area and/or volume of the object;
  c) determine how changes in area and/or volume of an object affect one or more dimensions of the object; and
  d) solve real-world problems about similar geometric objects.
