If a geometric figure undergoes a dilation with scale factor $k = 3$, the lengths of its sides are tripled. What happens to the interior angles of the image?

Which of the following best explains why the vertical height $h$ cannot be used directly as the height of the triangular faces when calculating a pyramid's surface area?

True or False: If a figure is first reflected across the $x$-axis and then translated by the vector $\begin{pmatrix}2\\3\end{pmatrix}$, the final image is congruent to the original pre-image.

Consider a cone with base radius $r$ and vertical height $h = r$. A sphere also has radius $r$. What is the ratio of the volume of this specific cone to the volume of the sphere?

True or False: If a sphere has a volume of $V$, then the volume of the smallest cylinder that can circumscribe it is exactly $\frac{3}{2}V$.
