Answer:
105 pi m^2
Step-by-step explanation:
radius squared - radius squared = 
(16+3)^2 - 16^2 = 
19^2 - 16^2 = 
361-256= 105

Answer:
The correct answer is 4.8 meters.
Step-by-step explanation:
Jamal stands on a dock 1.5 meters above the surface of the water.
A trout swims 4.8 meters below Jamal.
The trout must be swimming below the surface of water.
Therefore the distance below the surface of water where the trout is swimming is 4.8 - 1.5 = 3.5 meters.
But the vertical distance between Jamal and the trout is 4.8 meters only.
 
        
             
        
        
        
Answer:
3+6×(5+4÷2)-7  
Step-by-step explanation:
To solve the expression use order of operations.
Right now the expression solves to:
3+6×5+4÷2-7                  6* 5 = 30
3 + 30 + 4÷2-7                4 ÷ 2 = 2
3 + 30 + 2 - 7                   Add and subtract left to right.
33 + 2 - 7
35 - 7
28
To make it solve to 38, add parenthesis:
3+6×(5+4÷2)-7                (5+4÷2) = 7
3+6×(7)-7                        6*7 = 42
3 + 42 - 7                        Add and subtract from left to right
45 - 7
38
