A can of tuna has a diameter of 8 cm and a height of 3 cm. What is the volume if it is filled at 90% capacity? Use 3.14 for π.

The volume of the can of tuna is 37.98 cubic inches.

Step-by-step explanation:

V=πr^2(h)

V=(3.14)(2 in)^2(3 in)

V=(3.14)(4 in)(3 in)

V=(3.14)(12 in^2)

V=37.68 in^3

yes yes yes

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
