Answer:
10.2π
Step-by-step explanation:
Given data
Area of circle= 81 ft^2
Also, the expression for the area of a circle is
A=πr^2
substitute
81=3.142*r^2
r^2= 81/3.142
r^2= 25.77
square both sides
r= √25.77
r= 5.1
Also, the expression for the circumference is
C= 2πr
C= 2*π*5.1
C= 10.2π
Hence the circumference is 10.2π
20,814.00

Multiply both sides by 2.54.
Multiply both sides by x.
x = 60.96
Hence, Aaron needs 60.96 centimeters of wire.
