how do you determine the height for the inscribed questions for example in this question:

How could you tell that the height of the triangle was h-10? (why is it not h/2)

why couldn't you assume that r was also 10 cm even though the radius throughout a circle is uniform?

vs a problem like this where the height is h/2? (why is is not h-6?)

Does this help? Sorry about the sloppiness...trying out some new tech! At the beginning i say "h minus 2"...should've been "h divided by 2". Also, just noticed the volume is pretty low, so don't forget to turn your volume back down when you're done!
