work out the surface area of this cylinder with the raduics of 10 and the height of 22 give you answer in term of pipe

640π units squared.

Step-by-step explanation:

The formula for the surface area of a cylinder is 2πrh+2πr².

Where r is the radius and h is the height.

2πrh+2πr²

Apply the formula.

= 2π(10)(22)+2π(10)²

Multiply the terms.

= 440π+200π

Add both terms.

= 640π

The answer in terms of π is 640π units squared.

Solution,

Radius(r)=10

height(h)=22

Now,

hope this helps...

Good luck on your assignment..

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;

she will travel a distance in the range of 3 - 11 miles
