Complete Question
When the Olympic Games were held outside Mexico City in 1968, there was much discussion about the effect the high altitude (7340 feet) would have on the athletes. Assuming air pressure decays exponentially by 0.5% every 100 feet, by what percentage is air pressure reduced by moving from sea level to Mexico City?
Round your answer to one decimal place.
....... %
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The height of Mexico city is h = 7340 feet
The rate at which air pressure decays is 0.5% per 100 feet
From the data given

Answer:
A) The volume of solid is 18π cubic unit.
B) The volume of sphere is
a = -r , b = r , and
Solution A)
The given curve, rotate about x-axis between 2 to 4.
Please find attachment for solid figure or rotation.
Using disk method to find the volume rotation about x-axis
where, a = 2, b= 4 , and dx is thickness of disk.
Hence, the volume of solid is 18π cubic unit
Solution B)
The equation of circle of radius r and centered at origin (0,0).
The solid form is sphere of radius r.
Using disk method, to find volume of solid
where, a = -r, b = r , and dx is thickness of disk.
Hence, the volume of sphere is
