To approximate the volume of the cylinder using \( \pi \approx 3.14 \), we can follow these steps:
1. Start with the expression for the volume:
\[
\text{Volume} = 75\pi \, \text{ft}^3
\]
2. Substitute \( \pi \) with \( 3.14 \):
\[
\text{Volume} \approx 75 \times 3.14 \, \text{ft}^3
\]
3. Calculate the multiplication:
\[
75 \times 3.14 = 235.5
\]
So, the approximate volume of the cylinder is:
\[
\approx 235.5 \, \text{ft}^3
\]
