Answer: d=3
Step-by-step explanation: 3 times 3 is 9
9 times 3 is 27
 
        
                    
             
        
        
        
2m 
I think it is because the down it is 8 m 
so there is 6m it the top 
so it should be 
8-6=2
 
        
             
        
        
        
First one:
The circumference of the whole circle is (2π x the radius), 
and 60° is (60/360) = 1/6 of the whole circumference.
Second one:
The area of the whole circle is (π x the radius²), and
the 40° sector is (40/360) = 1/9 of the whole area.
I hope this is enough help.
        
             
        
        
        
Answer:
22.5°
Step-by-step explanation:
The <em>inscribed angle theorem </em>tells us that the measure of an inscribed angle is half of the central angle swept out by the same arc. Here, the arc BD sweeps out a central angle of 45°, so the measure of angle BAD must be half that, or 45/2 = 22.5°
