The formula for the volume of a cylinder is given by:
V = πr^2h
where V is the volume, r is the radius of the circular base, and h is the height of the cylinder.
We can find the radius of the cylinder by dividing the diameter by 2. So, the radius is:
r = d/2 = 2 feet/2 = 1 foot
Substituting the values of the radius and height into the formula, we get:
V = π(1 foot)^2(5 feet) = 15.71 cubic feet (rounded to two decimal places)
Therefore, the measurement that is closest to the volume of the cylinder in cubic feet is 15.71 cubic feet.
