    Radius of circle = 6 since the triangles are equilateral. So circumference = 2(6)pi=12pi

    I got 8.3 for the apothem of the pentagon. Your setup seems to be right. Also you need to pay more attention to the form of the answers in both questions.

    \[\tan 36=\frac{6}{b}\] \[b \tan 36=6\] \[b=\frac{6}{\tan 36}=8.3\]

    Therefore the area of the pentagon = 5(1/2)(12)(8.3)=247.7

    The reason is that we did not agree on the apothem. Did you see what I said about the apothem?

    The pyramid is composed of the base which is a pentagon and 5 sides which are 5 congruent triangles. If it said lateral surface area it would be just the 5 triangles but it says surface area so we have to assume it means all of the surfaces.
