C=pid
d=diameter
d=4
C=4pi
tada
if you want
aprox pi=3.14
C=12.56 units
        
             
        
        
        
The Z-score is calculated by the formula below

Step 2: Substitute the given parameters in the formula

Hence, the z-score of a person who scored 145 on the exam is -0.5
 
        
             
        
        
        
Quantity of gasoline needed by a car to run 800 miles = 30 gallons 
Quantity of gasoline needed by a car to run 1 mile =
= 30 ÷ 800
= 0.0375 gallons 
So , to run 1 mile a car would need = 0.0375 gallons of oil 
To run 700 miles the quantity of gasoline needed =
= 700 × 0.0375
= 26.25 gallons of gasoline 
Therefore , a car will use 26.25 gallons of gasoline on a trip of 700 miles .
