The answer is the range. The outliner is anything that “lies outside.” Range is the highest#-lowest#. So 78-28 = 50, which is not close the numbers that occurred most often (in this case, the #s in the 30s).

I don’t know how to use the triangle area to calculate the area of the inscribed polygons
Trava [24]

First of all, let's recall the area of a triangle, knowing its base (b) and height (h):

A = \cfrac{bh}{2}

The exercise is showing you that, if you inscribe a polynomial with more and more side, the area of the polynomial will approximate the area of the circle better and better (you can see youself that the polygon is "filling" the circle more and more as the number of sides increase).

Now, the second column tells you the area of each of the triangles the polygon is split into. So, we can see that the first polygon is split into 3 triangles, each of them having base 1.73 and height 0.5.

So, the area of each triangle is

A = \cfrac{1.73 \cdot 0.5}{2} = 0.4325

There are three of these triangles, so the area of the whole polygon is

A = 0.4325 \cdot 3 = 1.2975

In the second case, you have six triangles, each with base 1 and height 0.87. So, the whole area is

A = 6 \cdot \cfrac{1\cdot 0.87}{2} = 0.87 \cdot 3 = 2.61

Finally, in the last case you have 8 triangles, each with base 0.77 and height 0.92. So, the whole area is

A = 8 \cdot \cfrac{0.77\cdot 0.92}{2} = 0.77\cdot 0.92 \cdot 4 = 2.8336
