The formula for volume of a cylinder is:
Volume = PI x r^2 x h, where r is the radius and h is the height.
Volume = PI x 18^2 x 40
Volume = PI x 324 x 40
Volume = PI x 12,960
The exact volume would be 12,960PI cubic ft.
The decimal answer would vary depending on what value of PI is used.
<em><u>The average would be 16.</u></em>
To calculate this, add all the values together then divide that sum by the amount of data values.
11+16+15+22=64
64÷4=16
14x-21y+42 should be your answer. hope it helps :)
Let m and n be any integers so that 2m and 2k are two even numbers.
The product is 2m(2k) = 2(2mk), which is even.
It is a rational number because 98.45 can be turned into a fraction.
