Ok so we know that the distance around the circle (or circumference) is equal to the diameter times pi. 
This means that 

d being the diameter,
This means that:

= 12.00028271
= 12 m
So the diameter of the circle is 12 metres.
Hope this helped
 
        
             
        
        
        
The width is basically the diameter, and all you have to do is divide by 2 to get the radius.B is the name for base. I think the formula for a triangle is 1/2 bh. and for the circle c=pieD i hope that helped!
        
             
        
        
        
Answer:
 y = 3x + 23 and 

Step-by-step explanation:
The first equation is 9x - 3y = - 69 and we have to write it in slope-intercept form.
Now, 9x - 3y = - 69
⇒ 3x - y = - 23 {Dividing both sides by 3}
⇒ 3x + 23 = y
⇒ y = 3x + 23 {Interchanging the sides} (Answer)
The second equation is x - 3y = - 6 and we have to write it in slope-intercept form.
Now, x - 3y = - 6
⇒ x + 6 = 3y
⇒ 3y = x + 6 {Interchanging the sides}
⇒ 
  {Dividing both sides by 3}
⇒

Answer:
2 is the coefficient
Step-by-step explanation:
 
        
                    
             
        
        
        
Range = -4= g(x)
Therefore, g(x) = -3x+2
 or, -4=3x +2
 or, 3x= -4-2
 or, 3x= -6
 or, x= -6/3 = -2
OPTION A is the correct answer.
