Answer:
172.7 sqft (square feet)
Step-by-step explanation:
SA = 2(pi)(r)(h) + 2(pi)r^2
Insert the radius and height to derive SA, then multiply by 10 for the total number of fenceposts.
SA= 2(3.14)(.5)(6)
Calculate
SA=14.39166
Then multiply by 12
The result is 172.7 sqft
Hope this helps!
As a fraction, 2.161616 is represented as 2 161616/1000000, and when simplified, it becomes 2 10101/62500.
Response:
Dimensions of the rectangular fence:
x = 14 ft
w = 7 ft
A = 98 ft²
Detailed explanation:
Dimensions of the rectangular fence:
x = length, and w = width
Then x = 2*w ⇒ w = x/2
Perimeter is
p = 2*x + 2*w
p = 2*x + 2* x/2
p = 2*x + x
3*x = 42
x = 14 ft and w = 14/2 ⇒ w = 7 ft
