Answer:
I think its A 
Step-by-step explanation:
Sin(20) = 0.91294525072 which in a fraction it would be 24/25
 
        
             
        
        
        
B. -.0006
C. .28
Multiply 3 and 2 and you would get 6 then move the decimal 4 places to the left and you would get .0006 
Multiply 7 and 4 and you would get 28 then move the decimal places 2 spaces to the left and you would get .28
        
             
        
        
        
100÷11=9.09090909
converting it it will be 9.1 miles per hour
        
             
        
        
        
Well the volume of the cylinder will be equal area of base time height 
V = pi(4)^2 *(12)
The formula for the volume of a sphere is V = 4/3 πr³.
