So in order to calculate the covariance from that, we use this correlation coefficient. Actually, it’s in there as R times the two sample standard deviations. So that’s what we’re doing here. RCL 1 is our 7, RCL 2 is our 11, and RCL 3 is our correlation coefficient.

If you have the whole data (or almost the whole) there are also another way how to calculate correlation. In this case you must use biased std which has n in denominator.
