what is the volume of this cone? diameter 22 mm height 19 mm round your answer to the nearest hundredth.

1 answer

To calculate the volume of a cone, you can use the formula:

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

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

Given:

  • Diameter = 22 mm, so the radius \( r = \frac{22}{2} = 11 \) mm
  • Height \( h = 19 \) mm

Now, substitute the values into the formula:

\[ V = \frac{1}{3} \pi (11)^2 (19) \] \[ V = \frac{1}{3} \pi (121) (19) \] \[ V = \frac{1}{3} \pi (2299) \] \[ V \approx \frac{1}{3} \times 3.14159 \times 2299 \] \[ V \approx \frac{1}{3} \times 7227.42359 \] \[ V \approx 2419.14119 \text{ mm}^3 \] \[ V \approx 2419.14 \text{ mm}^3 \]

Rounding to the nearest hundredth, the volume of the cone is approximately 2419.14 mm³.
