The image you uploaded seems to be a page from a mathematics or physics exam that includes a problem related to a cylindrical structure. The problem involves calculating various parameters based on the given structure. Here's a breakdown of the image and the relevant questions:

Observations:

• The image shows a cylindrical tank.
• The questions below the image likely pertain to the dimensions, volume, surface area, or other properties of this cylindrical tank.

Typical Problems Involving Cylindrical Tanks:

1. Surface Area Calculation:

   • Total surface area = $2\pi rh + 2\pi r^2$ where $r$ is the radius and $h$ is the height of the cylinder.
   • Lateral surface area = $2\pi rh$.

2. Volume Calculation:

   • Volume of the cylinder = $\pi r^2 h$.

3. Material Cost or Coverage:

   • Often involves calculating the surface area to determine the cost of painting or covering the cylinder.

4. Pressure or Structural Integrity:

   • If the tank is holding a fluid, the problem might involve calculating the pressure exerted by the fluid at various depths.

Steps to Solve:

1. Identify Given Parameters:

   • Read the dimensions (radius $r$, height $h$) from the problem statement.

2. Determine What is Asked:

   • If the problem asks for the volume, use the formula for volume.
   • If the problem asks for surface area, apply the surface area formulas.

3. Substitute and Solve:

   • Substitute the given values into the appropriate formula.
   • Solve for the required quantity.
