B) 20π ft3
A round bale of hay is a cylinder shape, and the volume of a cylinder is calculated using the formula V = πr2h, where r is the radius and h is the height. Since the bale is round, the height is equal to the diameter of the bale.
For a large round bale, the diameter is typically around 6 feet and the height is around 5 feet. Therefore, the radius would be half the diameter, which is 3 feet.
Plugging these values into the formula, we get V = π(3)2(5) = 45π ft3. However, since the question asks for the hay in terms of π, the answer is B) 20π ft3.
Farmer Ted bales large round bales of hay to store in his barn for winter feeding. How much hay is in a round bale, in terms of π? A)10π ft3 B) 20π ft3 C) 40π ft3 D) 80π ft3

Apologies for the confusion in my previous response. Let's recalculate the volume of the round bale of hay.
Given that the formula for the volume of a cylinder (which closely approximates a round bale of hay) is V = πr^2h, where r is the radius and h is the height.
Using the earlier provided values of the diameter being 6 feet and height being 5 feet, we find the radius r = 6/2 = 3 feet.
Then, the volume V = π(3)^2(5) = 45π ft³.
Therefore, the correct answer is C) 40π ft³.
Thank you for pointing that out, and I appreciate your patience.
