Use the image to answer the question.

A 3 D cylinder shows a base radius of 3 centimeters and perpendicular height of 5 centimeters. A right angle is formed at the center of the base.
Find the volume of the cylinder, in cubic centimeters. Use 3.14 for pi. Round your answer to the nearest tenth.

1 answer

To calculate 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.

Given:

  • The radius \( r = 3 \) cm,
  • The height \( h = 5 \) cm,
  • Using \( \pi \approx 3.14 \).

Now plug in the values:

\[ V = 3.14 \times (3^2) \times 5 \]

Calculating \( 3^2 \):

\[ 3^2 = 9 \]

Now substitute back into the volume formula:

\[ V = 3.14 \times 9 \times 5 \]

Calculating \( 9 \times 5 \):

\[ 9 \times 5 = 45 \]

Now multiply by \( 3.14 \):

\[ V = 3.14 \times 45 \]

Calculating \( 3.14 \times 45 \):

\[ 3.14 \times 45 = 141.3 \]

Thus, the volume of the cylinder is:

\[ \boxed{141.3} \text{ cubic centimeters} \]
