What is the volume of an equilateral triangular pyramid with a side length of 8 cm and an altitude of 12 cm?

256 cm³

Step-by-step explanation:

Here, V = (1/3)(area of base)(height), and the numbers here are

          V = (1/3)(64 cm²)(12 cm) = 256 cm³

The first graph (ellipse) is not a function.

Step-by-step explanation:

Consider the provided graphs.

We need to determine which is not a function.

The vertical line test can be used to determine whether a graph represents a function.

If the vertical line intersect the graph more than one point then the graph is not a function.

Now consider the figure 1.

The first graph intersect the vertical line 2 times.

Therefore, the first graph (ellipse) is not a function.
