Question

Dan is planning a vacation and needs to purchase enough feed to fill the barrel in his pasture so that his cows will not be hungry while he is away. If the feed barrel is 7 feet high with a radius of 4 feet, what is the volume of feed the barrel can hold?

Answer 1

The formula for a cylinder is PieR^2H (Pi x Radius squared x Height).
Given the standard form of pi is 3.14, the height is 7, and the radius is 4, we can solve this easily.
The answer is 351.85 ft.
