Twelve disks with the given measurements are stacked on top of each other. which expression does not give the volume of the cylinder that is formed?

The correct option is 2.

Step-by-step explanation:

It is given that twelve disks with the given measurements are stacked on top of each other.

From the figure it is noticed that the radius of the disk is 3 cm and the height of disk is 1 cm.

The volume of a cylinder is

Volume of a disk is

The volume of 12 disk is

Option 1 represents the volume of stack.

The volume is 12 times of the volume of disk.

Option 3 represents the volume of stack.

The volume of a prism is the area of base multiplied by height.

Option 4 represents the volume of stack.

Therefore option 1, 3 and 4 are incorrect. So option 2 is correct.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
