The question is asking for the circumference
The equation for circumference is C=2(Pi)r

to find the radius, half the diameter 4/2=2

the equation is now C=2(Pi)2
simplify the equation...
C=4(Pi)
Pi is 3.1415926535897932384626433832795

Now multiply 3.1415926535897932384626433832795 times 4 = 12.566370614359172953850573533118
Round to nearest tenth...
