="Circumference of the circle"=Circumference of the circle

Explanation:

The formulas of the Circumference of the Circle (C)(C), the Perimeter of the Rectangle (P)(P) and the conditions provided herein are the following:

"Formulas"Formulas
C=2Pir
P=2(L+W)

"Conditions"
L=d=2r
W=r=d/2
Knowing the formulas and the conditions provided herein help analyze and solve the problem. Plugging in the values to the formulas in terms of r; i.e.,

"Circumference of the Circle"
C=2Pir
where:
Pi~~3.1416
C=(2)(3.1416)(r)
color(red)(C=6.2832r

"Perimeter of the Rectangle"
P=2(L+W)
P=2(2r+r)
P=2(3r)
color(blue)(P=6r

Therefore, the "Circumference of the Circle" is 4.72% greater than the "Perimeter of the Rectangle".
