Emma is making a scale drawing of her farm using the scale 1 cm = 2.5 ft. In the drawing, she drew a well with a diameter of 0.5 centimeter. Which is the closest to the actual circumference of the well?

1cm = 2.5 ft
0.5 cm = 1.25 ft

Circumference = πD
Circumference = π(1.25)
Circumference = 3.93 ft

Answer: 3.93 ft
