Area ( If you know the circumference) :
C^2 / (4×3.14) Brackets are important! 
So you have to type :
53.38^2/(4×3.14) 
= 226.865
        
             
        
        
        
You have the correct answer being (-5,3). Simply add the parentheses around the point
        
             
        
        
        
Hey, you didn’t provide any picture or further context.
To solve for gradient, do (y2-y1)/(x2-x1)
So what do you think?
