A right cone shows a base radius of 5 centimeters and a perpendicular height of 9 centimeters. A right angle is formed with the diameter and the height at the center of the circular base.


What is the volume of the cone in cubic centimeters? Use 3.14 for pi. Round your answer to the nearest tenth. (1 point)

The formula for the volume \( V \) of a cone is given by:

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

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

From the problem, we have:

  • The radius \( r = 5 \) cm
  • The height \( h = 9 \) cm
  • Using \( \pi \approx 3.14 \)

Now, we can substitute these values into the volume formula:

\[ V = \frac{1}{3} \times 3.14 \times (5^2) \times 9 \] \[ = \frac{1}{3} \times 3.14 \times 25 \times 9 \] \[ = \frac{1}{3} \times 3.14 \times 225 \] \[ = \frac{1}{3} \times 706.5 \] \[ = 235.5 \]

Rounding \( 235.5 \) to the nearest tenth gives us:

\[ \text{Volume} \approx 235.5 \text{ cubic centimeters} \]

Thus, the volume of the cone is 235.5 cubic centimeters.
