Answer:
Step-by-step explanation:
We know that formula to calculate the circumference of a circle is given by :-
, where r is the radius of the circle.
Given: The radius of the circle :
Then , the circumference of a circle is given by :-
Hence, the approximate circumference of a circle with diameter equal to 8 ft =
-223
-210<-223
The answer to your question is : B = 5007
Formula
B = 1001.32t
t = 5 hours,
Then
B = 1001.32 (5)
B = 5006.6 ≈ 5007
