To calculate the circumference,the equation is : 2丌r
Thus,the equation of the above would be
2丌(1)
=2丌
2丌 should be the answer,however if you cannot type that,try the ones below:
If you are to find a value,we generally use 3.14 or 7/22 for 丌
therefore the answer could be 6.28 or 7/11 as well.
Hope it helps!
