Standard deviation is simply the square root of the variance.
We need to get the square root of each variance to see whether its standard deviation is greater than its variance.
A. 0.25 ⇒ √0.25 = 0.50B. 1.75 ⇒ √1.75 = 1.32C. 2.5 ⇒ √2.5 = 1.58D. 1.5 ⇒ √1.5 = 1.22
Among the choices, only A. 0.25 has a standard deviation that is greater than the variance. The standard deviation is 0.50

He shows the formula to find it which is 360/n, where n is the number of sides of the regular polygon. He goes on further to explain the formula by taking an 18-sided regular polygon as example and computes its exterior angle as 360/18, which is 20 degrees
