The image depicts a cylinder with a height of 15 cm and a diameter of 5 cm. The cylinder is lying on its side, with its axis of symmetry tilted at an angle to the horizontal. The top of the cylinder is visible, as well as the circular base. The base is shaded gray, and the center of the circle is marked with a black dot. A dotted line extends from the center of the circle to the right, and a vertical line extends from the top of the cylinder to the right. The length of the dotted line is 5 cm, representing the diameter of the base, while the vertical line is 15 cm, representing the height of the cylinder.Find the volume of the cylinder below. Use the approximation 3.14 for pi.

To find the volume of the cylinder, you can use the formula for the volume of a cylinder:

\[ V = \pi r^2 h \]

Where:

  • \( V \) is the volume
  • \( r \) is the radius of the cylinder
  • \( h \) is the height of the cylinder

Given that the diameter of the cylinder is 5 cm, the radius \( r \) is half of the diameter:

\[ r = \frac{5}{2} = 2.5 \text{ cm} \]

The height \( h \) of the cylinder is given as 15 cm. Substituting the values into the volume formula:

\[ V = \pi (2.5)^2 (15) \]

Calculating \( (2.5)^2 \):

\[ (2.5)^2 = 6.25 \]

Now substituting this back into the volume formula:

\[ V = \pi \cdot 6.25 \cdot 15 \]

Using the approximation \( \pi \approx 3.14 \):

\[ V = 3.14 \cdot 6.25 \cdot 15 \]

Calculating \( 6.25 \cdot 15 \):

\[ 6.25 \cdot 15 = 93.75 \]

Now substituting this into the volume calculation:

\[ V = 3.14 \cdot 93.75 \]

Calculating this gives:

\[ V \approx 294.375 \]

Therefore, the final volume (in cubic centimeters) simplifies to approximately:

\[ V \approx 294.375 \text{ cubic centimeters} \]
