This question is a CIRCUMFERENCE question...
The Formula you need is : ]
C = 2 x pi x r
OR
C = pi x d
[C - circumference, pi - standard 3.14 (what is usually used rounded for pi), r- radius, d - diameter]
Since you already know PI and the DIAMETER...
I would use
C = pi x d
OR
3.14 x 64
Answer = 200.96 cm (If you need the answer in another metric unit, you can move the decimal, as needed)
LEGEND: your calculation for PI is off! it is more like 3.141592...

The circumference of a circle is 2*pi*r -- where pi is approximately 3.14159. That means that the distance covered by one revolution would be about 204.20335 cm -- or 2.0420335 meters.

64 times pi = distance of 1 revolution in cm.
pi = 3.141635

Approximately 2.01 meters
The circumference is pi times 64 centimers.
If you use the value of pi as
3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510,
then the distance would be 64 cm x
3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510
= 201.06193 meters

You are looking for circumference of a circle
C = pi X diameter
C = 3.14 X 64
200.96 cm
