These are just a few of the things you will learn in 6th grade. You will learn how to write a two- variable equation, how to identify the graph of an equation, graphing two-variable equations. how to interpret a graph and a word problem, and how to write an equation from a graph using a table, two-dimensional figures,Identify and classify polygons, Measure and classify angles,Estimate angle measurements, Classify triangles, Identify trapezoids, Classify quadrilaterals, Graph triangles and quadrilaterals, Find missing angles in triangles, and a lot more subjects. <span><span><span>Find missing angles in quadrilaterals </span><span>Sums of angles in polygons </span><span>Lines, line segments, and rays </span><span>Name angles </span><span>Complementary and supplementary angles </span><span>Transversal of parallel lines </span><span>Find lengths and measures of bisected line segments and angles </span><span>Parts of a circle </span><span>Central angles of circles</span></span>Symmetry and transformations <span><span>Symmetry </span><span>Reflection, rotation, and translation </span><span>Translations: graph the image </span><span>Reflections: graph the image </span><span>Rotations: graph the image </span><span>Similar and congruent figures </span><span>Find side lengths of similar figures</span></span>Three-dimensional figures <span><span>Identify polyhedra </span><span>Which figure is being described </span><span>Nets of three-dimensional figures </span><span>Front, side, and top view</span></span>Geometric measurement <span><span>Perimeter </span><span>Area of rectangles and squares </span><span>Area of triangles </span><span>Area of parallelograms and trapezoids </span><span>Area of quadrilaterals </span><span>Area of compound figures </span><span>Area between two rectangles </span><span>Area between two triangles </span><span>Rectangles: relationship between perimeter and area </span><span>compare area and perimeter of two figures </span><span>Circles: calculate area, circumference, radius, and diameter </span><span>Circles: word problems </span><span>Area between two circles </span><span>Volume of cubes and rectangular prisms </span><span>Surface area of cubes and rectangular prisms </span><span>Volume and surface area of triangular prisms </span><span>Volume and surface area of cylinders </span><span>Relate volume and surface area </span><span>Semicircles: calculate area, perimeter, radius, and diameter </span><span>Quarter circles: calculate area, perimeter, and radius </span><span>Area of compound figures with triangles, semicircles, and quarter circles</span></span>Data and graphs <span><span>Interpret pictographs </span><span>Create pictographs </span><span>Interpret line plots </span><span>Create line plots </span><span>Create and interpret line plots with fractions </span><span>Create frequency tables </span><span>Interpret bar graphs </span><span>Create bar graphs </span><span>Interpret double bar graphs</span><span> </span></span><span> </span></span>
For common figures, the shape of a figure that revolves about a line which is at the base of the figure to give a 3 dimensional shape is the shape of the cross section of the 3 dimensional figure when the angle of revolution is 180° and half the shape of the cross section of the formed 3 dimensional figure, when the angle of revolution is 360°
The cross section of an hemisphere is a semicircle, therefore, the shape of an hemisphere is formed by rotating a semicircle 180° about the diameter (which is the straight line at the "base") of the semicircle
Therefore;
The correct option that gives the revolution that will generate the hemisphere is;
