1/12 hope it helps!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Step-by-step explanation:
h(t) = 841 - 16t
[Is this written correctly? The time is usually t^2, not t. I'll solve with the written equation, but check the equation]
The height at ground level is 0, so we want the value of t when h(t) = 0:
0 = 841 - 16t
-16t = -841
t = 53 seconds
One can also graph this formula and find the time to hit the ground at the point the line intersects the x axis (x = 0).
====
If the equation should have read h(t) = 841 - 16t^2, solve it as above, setting h(t) = 0.
t = (29/4) seconds
This can also be graphed.
Answer:
5430.85 square feet
Step-by-step explanation:
Height of the cylindrical part of the cilo = 25 feet
radius of the base cylindrical part of cilo = 8 feet
Now volume of cylindrical part of cilo =
Volume of cylindrical part of cilo =
= 
Now,
Height of the conical part of cilo = 6 feet
Radius of the conical part of cilo = 8 feet
Volume of the conical part of cilo =
=
Volume of the entire cilo =
since 
volume of entire cilo =
= 5430.85
