what is the volume of a cylinder that has the height of 10, and the base 3.

1 answer

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

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

where:

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

From your information, the height \( h \) is 10, and it seems you mentioned the base as 3, which I will assume to be the diameter. To find the radius \( r \), you need to divide the diameter by 2:

\[ r = \frac{d}{2} = \frac{3}{2} = 1.5 \]

Now, plug the values into the volume formula:

\[ V = \pi (1.5)^2 (10) \]

Calculating \( (1.5)^2 \):

\[ (1.5)^2 = 2.25 \]

Now plug this back into the volume formula:

\[ V = \pi (2.25)(10) = 22.5\pi \]

Using \( \pi \approx 3.14 \) for the calculation:

\[ V \approx 22.5 \times 3.14 \approx 70.65 \]

So, the volume of the cylinder is approximately:

\[ 22.5\pi \text{ cubic units, or } 70.65 \text{ cubic units (using } \pi \approx 3.14\text{)}. \]
