Question

To find the volume of a Cylinder, we would use this formula: V=πr2h


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
?



(1 point)

40π ft3

80π ft3

20π ft3

10π ft3

Answer 1

I don’t have the bale’s dimensions (radius or diameter and height), so I can’t pick one of the choices yet. Use V = πr^2h:

- If you know the diameter, divide by 2 to get r.
- Then compute r^2 · h; the volume is π·(r^2·h) ft^3.

Examples:
- If r = 2 ft and h = 5 ft → V = π·(2^2)·5 = 20π ft^3.
- If r = 4 ft and h = 5 ft → V = π·(4^2)·5 = 80π ft^3.
- If r = 2 ft and h = 10 ft → V = 40π ft^3.

Give the bale’s diameter (or radius) and its length/height and I’ll pick the correct answer.
