It’s the second one. The symbol means “less than or equal to,” so it would be a closed circle with the arrow pointing to everything less than -1
        
                    
             
        
        
        
Answer:
8.5 inches and 34 inches
Step-by-step explanation:
Area of the square = 72.25
side² = 72.25
side = \sqrt{72.25}
 
Side = 8.5 in
Perimeter = 4 × side
Perimeter = 4 × 8.5 in
Perimeter = 34 in
 
        
             
        
        
        
Franck's answer is better (using ~), but I just wanted to point out that the conditional in yours is slightly redundant. It's easy to forget that, since you already have a boolean value, you don't need to perform a comparison in your conditional. So you could have just done this...
<span>if x
x = false;
else
x = true;
<span>end</span></span>
 
        
             
        
        
        
Answer:
452.39 mm^2 
Step-by-step explanation:
Area of a circle =  r^2
 r^2 
Here r = 12mm
Therefore, Area=  x 12^2 = 452.389342...
 x 12^2 = 452.389342...
Round to required degree of accuracy = 452.39mm^2
