The radius is 7 if the diam. is 14. We can find the surface area (without top or bottom areas) by finding the circumference of the base and then multiplying it by the height:
C=pi*d = pi(14); height = 9. Then the surface area of the side(s) is 14(pi)(9).
If you wish to include the areas of the top and bottom of the cylinder, add
2(pi)r^2 = 2(pi)(7)^2.

Answer:
The test statistic for this hypothesis test for a proportion is z=1.90.
Step-by-step explanation:
This is a hypothesis test for a proportion.
The claim is that the unemployment rate is less than 5%.
Then, the null and alternative hypothesis are:
The sample has a size n=1500.
The sample proportion is p=0.061.
The standard error of the proportion is:
Then, we can calculate the z-statistic as:
Please plot these 3 points on graph paper. This will result in a triangle with three different vertices. Which vertex corresponds to the largest interior angle of the triangle? to the smallest? If you can answer these questions properly, then you'll pretty much have the answer to this question. Be sure to arrange the sizes of the angles in ascending (increasing) order.
Answer:
she has 90 feet of ribbon in total and she can cut 270 pieces
Step-by-step explanation:
there's 108 inches in 9 feet
108/4=27
now you have 10 rolls so multiply
27x10=270 ribbons
you have 10 rolls of 9 feet to make ribbons
10x9=90 feet
