We have that
the Volume of cone=(1/3)*B*h
B=the area of the base
h= the height of the cone
D=3.5 in-----------------> r=D/2=1.75 in
h=5 in
B=pi*r²---------> 3.14*1.75²=9.616 in²
V=(1/3)*9.616*5=48.08 in³--------> 48 in³
the answer is 48 in³
        
                    
             
        
        
        
Answer:
Value of the car is decreasing by 13.9% each year.
Step-by-step explanation:
This equation tells us V(t) is the value of the car after a certain time in years, $21,000 is the initial value of the car.  What we need to focus on is on the 0.861 part of this equation.  This means that the price of the car is worth 0.861 or 86.1% of what it was worth the year prior, this means that the price of the car is decreasing over time.  By how much is it decreasing? Well if we consider 1 to mean 100% (since 100 / 100 =1) then we have 100%-86.1%=13.9%.  This means that the value of the car is decreasing 13.9% each year.
 
        
             
        
        
        
Answer:30 feet.
Step-by-step explanation: 2 doubled is four and in the bigger triangle it says 5. Therefore 12 doubled and a bit more is 30
 
        
             
        
        
        
Dy/dx = -y inx iny
(y in x in y) dx + dy = 0
(y in x in y ) dx = - dy
(in x )dx =  - (1/ y in y) dy
you just need to integrate both sides
Hope this helps
