The vertex is the point where the graph is horizontal, which you can find by setting the first derivative to zero.
derivative: -4x + 8 = 0 => x=2
fill it in in the equation:
y=-2*2² + 8*2 - 5 = 3
So the answer is the point (2,3)

The height of a semisphere is equal a radius of this hemisphere.
But... if we can talk about the height of the hemisphere ;)
R = 0.8m = 80cm then height of hemisphere is equal 0.8m = 80cm.
