Fruntum A bucket is 20cm in diameter at the open end,12cm in diameter at the bottom, and 16cm deep. To what depth would the bucket fill a cylindrical tin 28cm in diameter?

The depth is 5.33cm

Step-by-step explanation:

Given

--- diameter at open end

--- diameter at bottom

-- depth

--- diameter of the cylinder

Required

The depth the bucket will fill the cylinder

First, calculate the radii at the ends of the bucket

The volume of the bucket (frustum) is:

The volume of a cylinder is:

Where:

So, we have:
