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

Uhhhhhh
Answer: option B is correct.
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis represent
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
The line passes through (- 5, - 2) and (3, - 1),
y2 = - 1
y1 = - 2
x2 = 3
x1 = - 5
Slope,m = (- 1 - - 2)/(3 - - 5) = 1/8
To determine the intercept, we would substitute x = 3, y = - 1 and
m = 1/8 into y = mx + c. It becomes
- 1 = 1/8 × 3 + c
- 1 = 3/8 + c
c = - 1 - 3/8 = - 11/8
The equation becomes
y = x/8 - 11/8
