Question

A cylinder has a radius of 3 feet and a height of 2.1 feet.
What is the approximate volume of the cylinder?
Use 3.14 for pi.
12.6 ft
59.3 f
237.5 f
8550.2f

Answer 1

The volume \( V \) of a cylinder can be calculated using the formula:

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

where:
- \( r \) is the radius,
- \( h \) is the height,
- \( \pi \) is approximately 3.14.

Given the radius \( r = 3 \) feet and height \( h = 2.1 \) feet, we can plug in these values:

\[
V = 3.14 \times (3^2) \times 2.1
\]
\[
V = 3.14 \times 9 \times 2.1
\]
\[
V = 3.14 \times 18.9
\]
\[
V \approx 59.346
\]

Rounding to one decimal place, the approximate volume of the cylinder is:

\[
V \approx 59.3 \text{ cubic feet}
\]

Therefore, the answer is **59.3 ft³**.
