FAN, MEDAL What is the approximate circumference of a circle with a diameter of 400 inches?

You tell the answer

OpenStudy (imstuck):

Again, the circumference of a circle is C = pi * d where d is the diameter. Approximate probably means they want you to use 3.14 as pi, I would assume. C = (3.14)(400). What does that equal? I would round to maybe 3 or 2 places for accuracy.
