1. **State the problem:** We have two cylindrical containers, A and B.
Container A: diameter = 12 ft, height = 19 ft, initially full of water.
Container B: diameter = 14 ft, height = 13 ft, initially empty.
Water is pumped from A to B until B is full. We need to find the volume of empty space left in A after pumping.
2. **Formula for volume of a cylinder:**
$$V = \pi r^2 h$$
where $r$ is the radius and $h$ is the height.
3. **Calculate volume of Container A:**
Radius $r_A = \frac{12}{2} = 6$ ft
Height $h_A = 19$ ft
$$V_A = \pi \times 6^2 \times 19 = \pi \times 36 \times 19 = 684\pi$$ cubic feet
4. **Calculate volume of Container B:**
Radius $r_B = \frac{14}{2} = 7$ ft
Height $h_B = 13$ ft
$$V_B = \pi \times 7^2 \times 13 = \pi \times 49 \times 13 = 637\pi$$ cubic feet
5. **Water pumped from A to B:**
Since B is filled completely, volume pumped = $V_B = 637\pi$
6. **Volume left in A after pumping:**
$$V_{left} = V_A - V_B = 684\pi - 637\pi = (684 - 637)\pi = 47\pi$$ cubic feet
7. **Calculate numerical value:**
$$47\pi \approx 47 \times 3.1416 = 147.0$$ cubic feet (to nearest tenth)
**Final answer:** The volume of the empty space inside Container A after pumping is approximately **147.0** cubic feet.
