Answer:
A. 300π units³
Step-by-step explanation:
Formula for volume of a cone = ⅓πr²h
Where,
radius (r) = ½(10) = 5 units
height (h) = 36 units 
Plug in the values and find the volume in terms of π
Volume of the cone = ⅓*π*5²*36
Volume of the cone = 300π units³
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The dimensions of the rectangle are represented by functions:

The area is length × width of a rectangle.


Expand brackets and solve.


 
        
                    
             
        
        
        
Answer:
+ 6 
Step-by-step explanation:
(-2)·(-3) = + 6 
(-)·(-) = +
 
        
                    
             
        
        
        
Order.
9, 12, 12, 14, 15, 16, 18, 21
Now split into quarters.
9, 12, 12, 14, 15, 16, 18, 21
          |          |           |
        (1)                   (3)
Determine the values of (1) and (3) by using medians.
14 + 12 + 12 + 9 / 4
47 / 4
approx. 12
So Q1 = 12.
15 + 16 + 18 + 21 / 4
70 / 4
approx. 17
Therefore the answer is C I think. I have not done this ever before. All the knowledge I did was from research lol
