Needing to find the circumference of a circle you you find that you need to use the equation C=2 π R 
C= 28.26 
this is how much fence they would need around the garden approximately.
        
             
        
        
        
I think it would be 120 because it is 2 times 60 and they add up to 180 I may be wrong buts that’s what I would do
        
             
        
        
        
Answer:
We can call the amounts of red, gray, and brown dye 1 1/8x, 3/4x and 5/8 x respectively and we can write the equation:
1 1/8x + 3/4x + 5/8x = 20
2 1/2x = 20
x = 8 which means that the stylist needs 1 1/8 * 8 = 9 oz red, 3/4 * 8 = 6 oz gray and 5/8 * 8 = 5 oz brown.
 
        
             
        
        
        
Answer:
let dimention of original garden be x
then (x-8)(x-5) = 180
 x^2 -13x -140 = 0 
 (x-20)(x+7)=0
 x= 20 or x = -7 
 x = 20
 original area = (20)^2 
 = 400 m^2
 
        
             
        
        
        
Answer:
59 ° F
Step-by-step explanation:
F = 9/5 C + 32 
  = 9/5 (15) + 32 = 59 °  F
