Answer:
244.92 ft^2
Step-by-step explanation:
Find out the surface area of 1 fence post.
It has 2 circular parts (a bottom and a top)
r = d / 2
r = 1 / 2
r = 0.5 feet.
Area = 3.14 * 0.5^2
area = 3.14 * 0.25
Area = 0.785
Each post has 2 such shapes. 2 * 0.785 = 1.57
There are 12 posts with areas of 1.57 on the bottom and top = 18.84 ft^2
Find the area of the long part of the post
h = 6 feet
circumference = 2* pi * r
circumference = 2* 3.14 * .5
circumference = 3.14
The height is 6 feet.
The area of the body of the pole 6 *circumference = 6 * 3.14 = 18.84 ft^2
There are 12 poles.
Total area = 12 *18.84 ft^2 = 226.08
Total area = 12 bodies + 24 ends
Total area = 226.08 + 18.84
Total area = 244.92
Answer:
m = (y2 - y1) / (x2 - x1) | * (x2 - x1)
m * (x2 - x1) = y2 - y1 | + y1
m * (x2 - x1) + y1 = y2
Answer D is correct.
Answer:
39.16% probability of selecting three Democrats and three Republicans
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the order in which the people are selected is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
3 Democrats, from a set of 8.
3 Republicans, from a set of 8.
Total outcomes:
6 people from a set of 16.
Probability:
39.16% probability of selecting three Democrats and three Republicans
