                  6.  find the diameter of these objects.

                        a.                               b.                                c.

                                  Radius = 1 cm                    Radius = 24 cm                   Radius = 30 cm

                    7.  the following pizzas are cut into a different number of slices. Can you identify the
                        angle (acute, obtuse, or right) of a pizza slice in each case?

                        a.                       b.                      c.                         d.

                  8.  Write true or false for the following statements.

                        a.  A circle is a polygon.
                        b.  All radii (plural of radius) of a circle are of equal length.

                        c.  All diameters of a circle are of equal length.

                        d.  A circle has only one diameter.
                        e.  A circle has only one centre.

                        f.  The radius is half of the diameter of a circle.

                        There are different types of solids shapes, such as a cube, cuboid, cone, cylinder,
                         sphere, etc.
                        The net of a solid is a layout in a 2D shape that can be folded to form a 3D shape.
                        When two lines meet at a point, they create an angle.

                        A  simple closed  figure/shape  formed  by  three  or more  line  segments  is  called  a
                         polygon.
                        Polygons are named according to their sides.

                        The boundary of a circle is called the circumference.
                        The diameter is the longest straight line between any two points on the boundary of
                         a circle.
