Find the volume of a cylinder that has a diameter of

10
10 feet and a height of
25
25 feet. Use 3.14 for π.

1 answer

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 of the cylinder.

  1. Find the radius: The radius is half of the diameter. Given that the diameter is 10 feet, the radius \( r \) is:

\[ r = \frac{10}{2} = 5 \text{ feet} \]

  1. Use the height: The height \( h \) is given as 25 feet.

  2. Substitute the values into the volume formula:

\[ V = 3.14 \times (5)^2 \times 25 \]

  1. Calculate \( (5)^2 \):

\[ (5)^2 = 25 \]

  1. Substitute back into the equation:

\[ V = 3.14 \times 25 \times 25 \]

  1. Calculate \( 25 \times 25 \):

\[ 25 \times 25 = 625 \]

  1. Now calculate \( 3.14 \times 625 \):

\[ V = 3.14 \times 625 = 1975 \]

Thus, the volume of the cylinder is

\[ \boxed{1975} \text{ cubic feet}. \]
