Answer:
Circumference of circle = πd = π × 16 =16 π in.
or
circumference of circle = 2πr = 2×π×8= 16 π in.
16/2
According to PEMDAS
Multiplying/dividing comes first when you read the equation from left to right
The width of the walkaway be 4 feet.
<h3>What is Discriminant Formula?</h3>
The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equation
is D =
If D > 0, then the equation has two real distinct roots.
If D = 0, then the equation has only one real root.
Given that: 
also, area of walkaway = 464 square feet.
So, 

Using Discriminant method,
a=4, b=100, c=-464

w= 
w= 
So, 


Hence the width of the walkaway be 4 feet.
