A well with 10m inside diameter is dug 8.4m deep. Earth taken out of it is spread all around it to a width of 7.5m to form an embankment. Find the height of the embankment.

Explanation

To solve the problem step-by-step, we will find the height of the embankment formed by the earth dug out from the well.

### Step 1: Calculate the volume of the earth dug out from the well.
The well is a cylinder, and the volume \( V \) of a cylinder is given by the formula:
\[ V = \pi r^2 h \]
where \( r \) is the radius and \( h \) is the height (or depth in this case).
