Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any graph, so I could help you providing my own picture. As the statement says we have three triangles and want to know the total area and the area of one of them. The three triangles are congruent so we need to calculate just the area of one of them and multiply it by 3. Therefore:
<h2 />
TOTAL AREA (At):
AREA OF EACH TRIANGLE:
So the area of each triangle is:
The area of the cylinder is a function of its height (h) and radius, ()
The exact value of h is:
The given parameters are:
The surface area of a cylinder is calculated as:
Substitute values for Area
Divide through by pi
Substitute value for r
Collect like terms
Make h the subject
Rationalize
Hence, the exact value of h is:

Answer:
Below in bold.
Step-by-step explanation:
You do not say if the interest is simple or compound.
Simple Interest: I = PRT/100
= (8600* 2.6 * 4)/ 100
= $894.40.
Compound Interest:- amount after 4 years
= 8600(1 + 0.026)^4
= $9529.89
So the compound interest
= 9529.89 - 8600
= $929.89.
