Question:

Solution:

If exactly 12 cookies fit into the cylindrical cylinder. Let the thickness of the cookie be t, then we have the following equation:

$Volume\text{ cylinder = }12\text{ x volume }of\text{ cookie}$

that is:

$176.715\text{ = }12\text{ (}\pi\text{( }(5)/(2))^2t)$

this is equivalent to:

$75\pi t\text{ = }176.715$

solving for t, we get:

$t\text{ = }(176.715)/(75\pi)\text{ = 0.75}$

so that, the correct answer is:

$t\text{ = 0.75}$
