Question: 1 / 400

What is the volume in liters of a cylinder that is 10 inches in height with a diameter of 4 inches?

2.5 liters

3.78 liters

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

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

where \( V \) is the volume, \( r \) is the radius, and \( h \) is the height.

First, the cylinder has a height of 10 inches and a diameter of 4 inches. To calculate the radius, you divide the diameter by 2:

\[ r = \frac{4 \text{ inches}}{2} = 2 \text{ inches} \]

Now, you can substitute the radius and height into the volume formula:

\[ V = \pi (2 \text{ inches})^2 (10 \text{ inches}) \]

\[ V = \pi (4 \text{ inches}^2) (10 \text{ inches}) \]

\[ V = 40\pi \text{ cubic inches} \]

Calculating the volume in cubic inches gives approximately:

\[ V \approx 40 \times 3.14 \approx 125.6 \text{ cubic inches} \]

Next, to convert cubic inches to liters, we use the conversion factor where 1 cubic inch is approximately 0.0163871 liters:
