Respuesta :

EEPJR
Circumference = 2*pi*r
C = 2*3.14*r
C = 2*3.14*(d/2)
C = 3.14*d
C = 3.14*40 ft.
C = 125.6 ft.

Answer:

The answer is actually 125.6ft^2

Step-by-step explanation:

Following the equation for the circumference of a circle.

C = 2 * pi * r

C = (2)(3.14)(20)

C = (6.28)(20)

C = 125.6ft^2

The guy above me is 100% correct.
