Answer:
53.44 cubic meters
Step-by-step explanation:
A cylindrical oil drum is 2.1 meters high and has a radius of 0.9 meters. How many cubic meters of oil can the drum hold? (volume)
Volume of a cylinder = π × r² × h
r = 0.9 meters
h = 2.1 meters
= π × (0.9m)² × 2.1m
= 53.44 cubic meters
Therefore, the volume of the cylindrical oil drum = 53.44 cubic meters

Answer:
0.020
Step-by-step explanation:
Given that,
μ = 17,
σ = 0.7,
x¯ = 16.7 hours
n(number of batteries) = 30
To find,
The probability(e) by using μ\frac{σ}{
} = normal cdf
∵ (E - 99, 16.7 , 17, 0.8/
)
The probability of getting a random sample of 30 batteries = 0.020
Hence, the claim is reasonable as only 2% of batteries are likely to last till 16.7 hours.
