The answer is 29, I just didn’t on my head right now.
Answer:
34.54 
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Height (h) = 3.7 km
Base radius (r) = 3 km
We can calculate the volume of mountain by using following formula,
So, volume of cone = (1/3)π
h
By putting the value in the formula, we get
= (1/3) π ×
× 3.7
= 11.1π
= 34.54 
Hence, the volume of the mountain is 34.54
.
Step-by-step explanation:
I think we are missing some information (angle F or B or a side length would be great).
but just the right angles are not enough to calculate specific numbers. they would depend on the angle F or e.g. the side length of AB.
without any further information F and AB can be freely changed without changing the known facts, but it changes also C, B, G
so, all I can say is C = 180 - B.
and that G = B.
