Question

A jar of salsa has a height of 6 inches and a radius 2 inches. Find the volume of the sales jar. Use 3.14 for pi.

18.84 cubic inches

22.608 cubic inches

75.36 cubic inches

56.52 cubic inches

Answer 1

To find the volume of a cylindrical jar, you can use the formula for the volume of a cylinder:

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

where:
- \( V \) is the volume,
- \( r \) is the radius, and
- \( h \) is the height.

Given:
- Height \( h = 6 \) inches,
- Radius \( r = 2 \) inches,
- Using \( \pi = 3.14 \).

Now, plug in the values:

\[
V = 3.14 \times (2^2) \times 6
\]

Calculating \( r^2 \):

\[
r^2 = 2^2 = 4
\]

Now substitute \( r^2 \) back into the formula:

\[
V = 3.14 \times 4 \times 6
\]

Now multiply \( 4 \) and \( 6 \):

\[
4 \times 6 = 24
\]

Now multiply by \( 3.14 \):

\[
V = 3.14 \times 24 = 75.36
\]

Therefore, the volume of the salsa jar is:

\[
\boxed{75.36} \text{ cubic inches}
\]
