True. Because the you will get all the areas of those 6 congruent triangles equally and so summing up them will give you the area of the hexagon.
No, because if the angles are the same the length is the same too. It is a scalene, obtuse triangle if you need that as well.
The probability is 1 in 36 because there are 36 possible rolling combinations.
First the 2 bases have surface area pi*1.25^2*2
Then the side
2.5pi*4=10pi
total of 9.817+31.415
=41.232
This approximation could be further round down for this problem to 41.2
Which makes choice C the correct choice.
