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

= > r = 17.85 divided by 2
r
= 2.84 [ taking
=
]
Step 3 :
Answer :
The radius of the given circle is 2.84 units
