1 answer

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

\[ V = \frac{1}{3} \pi r^2 h \]

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

  1. First, calculate the radius:

    • Since the diameter is 24 feet, the radius \( r \) is: \[ r = \frac{\text{diameter}}{2} = \frac{24}{2} = 12 \text{ feet} \]
  2. Next, plug the values into the volume formula:

    • We know \( \pi = 3.14 \) and \( h = 60 \) feet. \[ V = \frac{1}{3} \times 3.14 \times (12)^2 \times 60 \]
  3. Calculate \( (12)^2 \): \[ (12)^2 = 144 \]

  4. Now substitute this back into the volume equation: \[ V = \frac{1}{3} \times 3.14 \times 144 \times 60 \]

  5. Calculate \( 144 \times 60 \): \[ 144 \times 60 = 8640 \]

  6. Now, substitute this value back: \[ V = \frac{1}{3} \times 3.14 \times 8640 \]

  7. Calculate \( 3.14 \times 8640 \): \[ 3.14 \times 8640 = 27169.6 \]

  8. Finally, divide by 3: \[ V = \frac{27169.6}{3} \approx 9056.53 \]

Therefore, the volume of the cone is approximately:

\[ \boxed{9056.53} \text{ cubic feet} \]
