Answer:
The maximum volume of cone is 138.25 m³
m
m
Step-by-step explanation:
A right circular cone whose hypotenuse is m
It is revolved about one leg to generate a right circular cone.
Let radius be r m and height be h m
For right angle triangle,
Volume of generated cone
Differentiate w.r.t h
For maximum/minimum
<em>Using double derivative test </em>
At
so get maximum volume.
Dimension of cone:
m
m
The maximum volume of cone is 138.25 m³
Answer:
1) 512
Step-by-step explanation:
1st multiply 2x4 and get 8, then square 8, divide by 4 to get 512
<span>1 km 431 + 13 km 169m = 1431m + 13169m= 14,600 m = 14 km 600m</span>
Answer:
x=9.73
Step-by-step explanation:
This is trigonometry work! :)
So cos46°=x/14
x=14×cos46°
x≈9.73
Hope this helps <3
