Pi is a famous irrational number.
 
        
             
        
        
        
A(r)=3.14r^2, when r=5
A(5)=3.14(5^2)
A(5)=3.14(25)
A(5)=78.5 u^2
        
             
        
        
        
Answer:
1400 miles
Step-by-step explanation:
Speed is the time rate of change of distance. It is the ratio of distance to time and is given by the equation:

 plane averaged 400 mph on a trip going east, but only 280 mph on the return trip. 
The time spent (t₁) in going east is given by:

The time spent (t₂) in going east is given by:

The total time (t) = t₁ + t₂
t = t₁ + t₂ = 8.5 hours

Therefore the one way distance is 1400 miles
