The radius of the given circle  is 2.84 units 
Step-by-step explanation:
Step 1 :
Given 
The perimeter of a quarter table is 17.85
We need to find the circle's radius.
Step 2 :
The circle's perimeter is given by the formula, 2 
 r where r represents the circle's radius
So from this we have , 
2 
 r = 17.85
We can determine the radius by dividing the perimeter value by 2 
 
= >  r = 17.85 divided by 2 
 r
         = 2.84 [ taking  
  = 
]
Step 3 :
Answer : 
The radius of the given circle  is 2.84 units
