When finding volume of a cylinder use the formula V=pi r^2h

h=height = 2feet

r=radius = 6feet

V= pi(6)^2(2)

V=226.19

In order to do this find the area of either the base or the top it doesn't matter they're the same (thats just the area of one of the circles) then multiply that by the height so the answer is 226.08

Given

The weekly salaries of a sample of employees at the local bank are given in the table below.

Employee Weekly Salary Anja $245 Raz $300 Natalie $325 Mic $465 Paul $100.

<h3>Variance</h3>

Variance is the expected value of the squared variation of a random variable from its mean value, in probability and statistics.

The mean value of the salaries of employees is;

$\rm Mean= \dfrac{245+300+325+465+100}{5}\\\\Mean=287$

The variance is given by;

$\rm Variance=\sqrt{\dfrac{(245-287)^2 +(300-287)^2 +(325-287)^2 +(465-287)^2 +(100-287)^2}{5-2}} \\\\Variance = 132.316}\\\\On \ Squaring \ both \ the \ sides\\\\Variance^2=17,507. 5$
