The diameter of the circle is 18 cm.
The radius is one half the diameter.
Therefore the radius is  18/2 = 9 cm
Answer: 9 cm
        
             
        
        
        
Answer:
B
Step-by-step explanation:
Given
(4x + 3)(3x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
4x(3x - 4) + 3(3x - 4) ← distribute both parenthesis
= 12x² - 16x + 9x - 12 ← collect like terms
= 12x² - 7x - 12
The coefficient of the x- term is - 7 → B
 
        
             
        
        
        
Answer:
Approximately 9 units. 
Step-by-step explanation:
To find the distance between two ordered pairs, we can use the distance formula. The distance formula is: 

Let (2,-3) be x₁ and y₁ respectively, and let (-4,4) be x₂ and y₂, respectively. 

 
        
             
        
        
        
Answer:
The perimeter of a shape is the length around it.
Step-by-step explanation:
We will be using the x and y values and add them together to find the total perimeter. 
To do this, let's find all the values of the 2 axis:
(2 to 4) = 2
(1 to 3) = 2
(4 to 10) = 6
(3 to 1) = 2
(10 to 12) = 2
(1 to 8) = 7
(12 to 2) = 10
(8 to 1) = 7
We now add these values together which gives us <em><u>38</u></em>. Don't forget to add the units afterwards (cm, m and so forth).
