A farmer has three silos. The largest silo has a diameter of 24 feet. The radius of the smallest silo is one-thrid as big as the diameter of the largest. The middle sized silo has a radius that is 2 feet greater than the radius of the smallest silo. What is the circumference of each silo?

The circumference of the largest silo is 75.398 feet, the circumference of the middle sized silo is 37.70 feet and the circumference of the smallest silo is 25.132 feet.

Step-by-step explanation:

The given is,

                 A farmer has three silos

                 Radius of Largest silo = 12 feet

                 Radius of middle size silo = 6 feet

                 Radius of smallest silo = 4 feet

Step:1

          Formula for circumference,

           where, r - Radius

Step:2

           Circumference of Largest silo,

                          feet

           Circumference of Largest silo = 75.398 feet

Step:3

           Circumference of Middle size silo,

                          feet

          Circumference of middle size silo = 37.699 feet

Step:4

            Circumference of smallest silo,

                          feet

            Circumference of smallest silo = 25.132 feet

Result:

            The circumference of the largest silo is 75.398 feet, the circumference of the middle sized silo is 37.70 feet and the circumference of the smallest silo is 25.132 feet.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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;
