Shannon is designing a snowman for a winter mural. She wants the head of the snowman to have a radius of 5 inches (5in.), and the midsection of the snowman to have a radius of 7in. How much bigger is the area of the snowman's midsection than the area of its head? In other words, how many more square inches of material will be needed to create the midsection of the snowman compared to the square inches needed to create its head?

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

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;

50-60=10
