The circumference of a circle is diameter times 2, then times pi!
So the answer is 16(pi)!
That's easy...

In circles:
C = (pi)*d C = Circumfrence, d = diameter
You just have to substitute in the known values, and you're there.
Depending on your teach/prof, you may have to leave it in terms of pi, or you may be expected to give a numerical approximation to a certain number of decimal places.
Also, if you ever have the Circumfrence, and you are trying to find the diameter, just divide C by pi. Remember d = C/(pi)

Let C = circumference of circle.
Let D = diameter
C = D(pi)
C = 8(pi)
C = ~25.13

C = 2*pi*radius
radius = 4
C = 8 pi

Cirumference (C)= 2* 3.14159* r
circumference is equal to two, times pie, times radius.

C=APR
8axTT=25.12
25.12x4r=100.48
