Answer:
75.40 inches
Step-by-step explanation:
If it is its circumference, then the answer is self-evident, 24 inches. If it is its diameter, then we must do a little calculation, multiplying the diameter by Pi to reach 75.40 inches.
If you notice the picture below
the hexagonal pyramid, is really just a hexagon at the bottom, 6 sides,
and 6 triangles stacked up to each other at the edges
so.. just get the area of the hexagon and the triangles, and add them up, that'd be the surface area of the pyramid
a triangle's area, you'd know is just 1/2 bh, and you have both of those there
now, for the hexagon, notice, we're given the length from the center to one of the sides, namely the "apothem"
thus
