Select the solid whose cross sections are dilations of some two-dimensional shape using a point directly above the shape as a center and scale factors ranging from 0 to 1.

Cone

Step-by-step explanation:

Options:

a) Cone      b)  Cube     c)  Cylinder    d)  Triangular prism

From the given options (a) to (d), option (a) is true.

This is so, because.

The volume (V) of a cone  is:

This is as a result of dilating the cylinder by 1/3 whose volume is:

In other words:

i.e. the cross-section of the cylinder (V2) being dilated by 1/3 (which is between 0 and 1) gives the cone (V1)

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
