Answer:
172.7sqft (square feet)
Step-by-step explanation:
SA = 2(pi)(r)(h) + 2(pi)r^2
plug in the radius, height, and find SA, then multiply by 10 fenceposts.
SA= 2(3.14)(.5)(6)
Solve
SA=14.39166
Multiply by 12
Answer is 172.7sqft
Hope this helps!
Answer:
y=-3/4x
Step-by-step explanation:
the form is "y=mx(+/-b). m is slope. b is y-intercept.
You can use an input table x is the input and y is the output.
3(x) (y)7
3(1)=3 (3)7=21

Answer:
456.25m
Step-by-step explanation:
Since the question did not ask for what to find, we can as well look for the maximum height reached by the object
Given the height of an object thrown vertically expressed as;
s=-16t^2+100t+200.
At max height,
dS/dt = 0
-32t+100 = 0
-32t = -100
t = 100/32
t = 3.125s
Get the Max height
s(3.125) = -16(3.125)²+100(3.125)+200
s(3.125) = -156.25+312.5+200
s(3.125) = 456.25m
Hence the maximum height reached by the object is 456.25m
