Answer:

x = 8
AM = BM = 16

Step-by-step explanation:

Your problem setup is correct. The triangle is isosceles, so the marked segments are the same length.

3x - 8 = 2x

You can solve this by subtracting 2x (from both sides) ...

x - 8 = 0

Then adding 8 (to both sides):

x = 8

MB = MA = 2x = 16.

The rotation about UG would generate a hemisphere of radius 8. The volume of a sphere with radius $r$ is $\dfrac43\pi r^3$ , so the volume of the hemisphere would be $\dfrac12\cdot\dfrac43\pi 8^3\approx\dfrac{1024\cdot3.14}3\approx1071.79$ .
