40π ft^3
20π ft^3
80π ft^3
10π ft^3
explain which is the correct answer
The formula for the volume of a cylinder is V=πr^2h, where r is the radius of the base of the cylinder and h is the height. In this case, the given bale of hay is cylindrical with a diameter of 5 ft, so the radius (r) would be half of the diameter, which is 5/2 = 2.5 ft. The height (h) is given as 4 ft.
Plugging in the values into the formula, we get V=π(2.5)^2(4) = 40π ft^3.
Therefore, the correct answer is 40π ft^3.
