Answer:

Step-by-step explanation:
Given:
radius of cone = 3 inch
Total area of cone = 
Find the volume of the cone?
We know the area of cone =  -------(1)
 -------(1)
Where r = radius
Ans s = side of the cone
Put the area value in equation 1
 -------(1)
 -------(1)


Put r value in above equation.



The side s = 5 inches
We know the side of the cone formula


Put r and s value in above equation.




The volume of cone is

Put r and h value in above equation.

 
 
The Volume of the cone is 
 
        
             
        
        
        
Step-by-step explanation:
STEP 1
Equation at the end of step 1
 (((x3) - 22x2) + x) - 4 = 0 
STEP 2
Checking for a perfect cube
 2.1 x3-4x2+x-4 is not a perfect cube
<h3>Ans; x=4</h3>
 
        
             
        
        
        
Answer:
Difference in cash and plan = $155 - $149.50 = $5.50
Interest Rate = 3.68%
Step-by-step explanation:
Given:A food processor for $149.50 cash, or $5.00 down and $10.00 per month for 15 months
A food processor by cash = $149.50
Payment plan =  Down payment + $10*15 months
 = $5 + $10*15
= $5 + $150
Payment plan = $155
Difference in cash and plan = $155 - $149.50 = $5.50
Now we have to find the interest rate
= (difference/original)*100
= (5.50/149.50)*100
Interest Rate = 3.68%
 
        
             
        
        
        
Since we are asked for tge graph that represent the total cost for the x numbers of lesson, it will be helpful to illustrate it first this way
for each lesson it will cost $30 dollars
1 lesson $30 
2 lessons $60
3 lessons $90
4 lessons $120
5 lessons $150
 
So from this set of numbers , it is apparent that the grqph in letter c represents the total costs for x numbers of lessonsseethati
