Find the volume, in cubic inches, of a cone with a radius of 13 inches and a height of 27 inches. round your answer to the nearest hundredth. Use 3.14 for pi.

1 answer

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

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

where \( r \) is the radius and \( h \) is the height of the cone.

Given:

  • Radius \( r = 13 \) inches
  • Height \( h = 27 \) inches
  • Using \( \pi \approx 3.14 \)

Now, substituting the values into the volume formula:

\[ V = \frac{1}{3} \times 3.14 \times (13)^2 \times 27 \]

Calculating \( (13)^2 \):

\[ (13)^2 = 169 \]

Now plug that into the formula:

\[ V = \frac{1}{3} \times 3.14 \times 169 \times 27 \]

Calculating \( 169 \times 27 \):

\[ 169 \times 27 = 4563 \]

Now, substituting this back into the equation:

\[ V = \frac{1}{3} \times 3.14 \times 4563 \]

Calculating \( 3.14 \times 4563 \):

\[ 3.14 \times 4563 \approx 14317.82 \]

Now, dividing by 3:

\[ V \approx \frac{14317.82}{3} \approx 4772.61 \]

Therefore, the volume of the cone, rounded to the nearest hundredth, is:

\[ \boxed{4772.61} \text{ cubic inches.} \]
