Explanation: This question is testing your ability to determine the volume of a cylinder. The volume of a cylinder can be found by using the formula, v= πr²h
In this problem, r = 1.5 and h = 2.5, so
v = π(1.5)²(2.5)
v = π (2.25)(2.5)
v = π 5.63
v= 17.69, then round up to the nearest whole number to get 18.
