Into a circular drum of radius 4.2 m and height 3.5m, how many full bags of wheat can be emptied if the space required for wheat in each bag is 2.1 cubic m. (Take `pi=22//7)`

Explanation

To solve the problem, we need to find the volume of the circular drum and then determine how many full bags of wheat can fit into that volume.

### Step-by-step Solution:

1. **Identify the formula for the volume of a cylinder**:
The volume \( V \) of a right circular cylinder is given by the formula:
\[
V = \pi r^2 h
