0.005
Step-by-step explanation:
Im guessing you meant whats the average of 3,4,5, and 8. which would be 5.

A. sometimes
just because they have the same volume does not mean they are congruent. they could have different heights and base areas
hope this helps:)
Note that the given cos(57°)cos(94°)-sin(57°)sin(94°) resembles the formula
cos a cos b - sin a sin b, which is cos (a+b).
Therefore, cos(57°)cos(94°)-sin(57°)sin(94° = cos (57+94) = cos 151.
