It most common to round to the hundredths place, this is two spaces after the decimal. 
So look two spaces right - 0.17. If the third digit (in this case 6) is higher than 5 you round the number up if its not, keep it the same. 
"6" is greater than five, so round it to about (or approximately) 0.18.
        
             
        
        
        
Answer:
Step-by-step explanation:
Exterior angle property: Exterior angles equals the sum of remote angles
19x - 18 = 7x + 1 + 10x - 9
19x - 18 = <u>7x + 10x</u> + <u>1 - 9 </u>    {Combine like terms}
19x - 18 = 17x - 8          {Subtract 17x from both sides}
19x - 17x - 18 = -8
         2x - 18 = -8         {Add 18 to both sides}
               2x = -8 + 18
              2x = 10
               x = 10/2
x = 5
 
        
             
        
        
        
For this case we must find the area of the cookie, knowing that it has a circular shape. By definition, the area of a circle is given by:

Where:
r: It is the radius of the circle
According to the data we have:

Thus, the area of the cookie is:

We have 

We round:

Thus, the area of the cookie is
