Chapter 12.2, Problem 8WE

To determine

To draw: the pyramid.

Explanation of Solution

Given information:

A regular pentagonal pyramid with base edge $1.5$ and slant height $9$ .

Graph: since, A regular pentagonal pyramid with base edge $1.5$ and slant height $9$ .

Now to draw pyramid, first draw a parallelogram for the base and sketch diagonals and then draw a vertical segment at the point where the diagonal intersect and then join the vertex to the base vertices,

Thus, the pyramid can be obtained as:

  

Interpretation: form the above graph and side and height it can be observed that the lateral area of pyramid is $\text{33}\text{.75}$ .
