Answer:
(pi)4 or about 12.57 sq. units
Step-by-step explanation:
The base area of a cylinder is a circle.
Since we know that the radius is 2, we can use the equation A = (pi)r^2 to find the area.
So, using this formula, the area is (2)(2)(pi), about 12.57 sq. units (area is squared!)
 
        
             
        
        
        
Answer:
65.54% (nearest hundredth)
Step-by-step explanation:
Given:

P(X > 8600) = 1 - P(X ≤ 8600) 
                     = 1 - 0.3445782584
                     = 0.6554217416 
                     = 65.54%
 
        
             
        
        
        
14+36+h=400
    50+h=400
   -50       -50
---------------------
            h=350mm
        
                    
             
        
        
        
Start by getting the term with the exponent on one side

take the log of both sides

There is a log rule that says we can bring down the exponent

Solve for x

5x=6.64
answer: x=1.33
