Answer 2

If I remember right the area of the conical part is:
\[\pi r s\]

Answer 3

and the area of the base is
\[\pi r^2\]

Answer 4

So calculate those two and add them together fot the total area of the tent.

Answer 5

Surface Area = pi*10*14 + pi* (10)^2
Surface Area = 140 pi + 100 pi
Surface Area = 240 pi
Surface Area = 240*3.14 = 753.6 cubic feet approx
