Answer:
Area of a Circle = πr² 
R=Diameter/2 
=21mm 
=π(21)² 
=1385.44mm² 
To the nearest whole number 
= 1385mm² 
The answer is in mm². It may differ if the given answer is in m². You can get this by converting your radius to meters. This is done by dividing 21mm by 1000.

scalar multiplication, now, add them up
 
        
                    
             
        
        
        
The Domain of a function is described as the set of all the x values that a function can take.These are the allowable values of a function.
From the table we can see that the first column shows the x values for the function. So the set of all  values will be the Domain of the function.
Hence the Domain is {-2, -1, 0, 1}
So, option B gives the correct answer

Answer:
110 degrees
Step-by-step explanation:
to find the angle x, we need to use the formula to find the 50 degree angle:
(y - x) / 2 = 50
y is 210
(210 - x) /2 = 50
210-x = 100
x = 110 degrees
