Answer:
4π or about 12.56
Step-by-step explanation:
The circumference of a circle is calculated with diameter so we first need to find the diameter. Going from radius to diameter can be done by multiplying by 2, therefore 2*2=4 so the diameter is 4.
Now that we have the diameter we need to use the formula for circumference which is c=4*π. Because the question doesn't state to use 3.14 to multiply then you would usually use 4π as your answer but if you were to use 3.14 then you would get a circumference of 4*3.14=12.56.
