Answer:
200.96 ft²
Step-by-step explanation:
The question is on surface area of a closed cylinder
Formulae= SA=2 ×pi× r² + 2×pi×r×h
Where pi=3.14
SA= 2×3.14×2² + 2×3.14×2×14
SA=25.12+175.84
SA=200.96 ft²
The diagonal fencing will be the hypotenuse of a right triangle with sides 120yds long so:
h=√2(120^2))
h=√28800 yd
And the surrounding fencing will just be four times the side length of 120yds so:
s=480yd
So the total fencing needed is:
f=480+√28800 yards
f≈649.71 yd (to nearest hundredth of a yard) which is
f≈650 yds (to nearest whole yard)
But, I wasn't sure, if they just want the diagonal fencing needed then it is just:
f=√28800
f≈170 yds (to nearest yard)
Answer: $350
Step-by-step explanation:
$700 divided by 2 is 350
