@Louloubelle00 Your first question
6.png

is a regular hexagonal pryamid
the 6 sides are all triangles

the drawing shows they have a base of 15m and a height of 12m

What is the area of ONE of the triangles?
What is the area of SIX of the triangles?

When you have answered that I will help you to find the area of the base..

mrnood · Answer

Here is the help with formula:

The area of a triangle is HEIGHT * BASE/2

The drawing shows they have a BASE of 15m and a HEIGHT of 12m

What is the area of ONE of the triangles?
What is the area of SIX of the triangles?

mrnood · Answer

For your second question 
78.png

The area of a cone with Height h and radius r is

$$A = \pi r(r+ \sqrt{r ^{2}+h ^{2}})$$

In your question it tells you h= 43m and DIAMETER =14

SO 
h=43
r= 7

Put those numbers into the formula to get your answer
