X={6,-10} that is the answer
The first thing we are going to do for this case is to model the igloo as a hemisphere.
The volume of the hemisphere is:
V = ((4/3) * (pi) * (r ^ 3)) / 2
Where,
r: sphere radio
We have then that the internal diameter is:
di = 12-1.5
di = 10.5 feet
So the radio is:
r = di / 2
r = 10.5 / 2
r = 5.25 feet
Substituting values:
V = ((4/3) * (pi) * ((5.25) ^ 3)) / 2
V = 303.1 feet ^ 3
Answer:
the amount of space of the living area inside the igloo is:
V = 303.1 feet ^ 3
What is 0.00340.78 correct to 3 significant figures?
a significant fugure is when the number lean solething ,so its can anyone except 0
so if we are reducing 0.00340.78 to 3 significant number
first we have to look for the significant nulber ,which are 3,4,7,8
so the answer can be 0.0034.7
hopefully this helps
16 units just count the tiny lines in the middle by 2
