Here's the first one . . .
I assume the "lateral edge" is what most of us call the "slant height".1) Find the lateral area of a regular hexagonal pyramid
. . .if each edge of base is 10m and each lateral edge is 15m.
One of the triangular side panels looks like this:Code:* /|\ / | \ / | \ 15 / h| \ / | \ / | \ / | \ * - - - * - - - * 5
From Pythagorus: .
The area of this triangle is: .
Therefore, the area of the six panels is: .
