Answer:
530.93 square units
Step-by-step explanation:
The area of a circle in terms of diameter can be found by ...
A = (π/4)d²
A = 3.14159/4×26² ≈ 530.929
Rounded to hundredths, the area of the circle is 530.93 square units.
If you are considering all the vertices independently you will have a total of 8*10 = 80 triangles. You can figure out this way: the sum of the interior angles of a decagon = (2n-4)*right angles or (n-2)*triangles. So a decagon will form 8 triangles.
hope this helps...
