A hollow cylinder with the bottom end closed off is filled with 5.00 mL of water. The height of the water in the cylinder is 57.0 mm. How much will height of the liquid change after 277 microliters of water added.

We are tasked with finding how much the height of the liquid will change after 277 microliters (\(\mu L\)) of water is added to the cylinder.

### Given:
- Volume of water initially: \(V_1 = 5.00 \, \text{mL} = 5000 \, \mu L\)
- Initial height of water: \(h_1 = 57.0 \, \text{mm}\)
- Volume of water added: \( \Delta V = 277 \, \mu L\)

### Step 1: Calculate the cross-sectional area of the cylinder

The height \(h_1\) and the volume \(V_1\) are related by the formula for the volume of a cylinder:
\[
V_1 = A \times h_1
\]
Where:
- \(A\) is the cross-sectional area of the cylinder (constant),
- \(h_1\) is the height of the liquid,
- \(V_1\) is the volume of the liquid.

Rearranging the formula to solve for \(A\):
\[
A = \frac{V_1}{h_1}
\]

Substitute the known values (\(V_1 = 5000 \, \mu L\) and \(h_1 = 57.0 \, \text{mm}\)):
\[
A = \frac{5000 \, \mu L}{57.0 \, \text{mm}} = \frac{5000 \, \text{mm}^3}{57.0 \, \text{mm}} \approx 87.72 \, \text{mm}^2
\]

### Step 2: Calculate the change in height

The new volume of water after adding 277 \(\mu L\) will be:
\[
V_2 = V_1 + \Delta V = 5000 \, \mu L + 277 \, \mu L = 5277 \, \mu L
\]

The change in height \(\Delta h\) is given by the relation:
\[
\Delta h = \frac{\Delta V}{A}
\]

Substitute \(\Delta V = 277 \, \mu L = 277 \, \text{mm}^3\) and \(A = 87.72 \, \text{mm}^2\):
\[
\Delta h = \frac{277 \, \text{mm}^3}{87.72 \, \text{mm}^2} \approx 3.16 \, \text{mm}
\]

### Final Answer:
The height of the liquid will increase by approximately \(3.16 \, \text{mm}\).
