Standard deviation = square root of variance.

No, you have it backwards, the standard deviation is the square root of the variance, so the variance is the standard deviation squared. Usually you find the variance first, as it is the average sum of squares of the distribution, and then find the standard deviation by squaring it.

Standard deviation

The standard deviation is the square root of the variance.

The standard deviation is defined as the square root of the variance, so the variance is the same as the squared standard deviation.
