To find 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, and \( h \) is the height.

  1. The diameter of the cone is 20 cm, so the radius \( r \) is half of the diameter:

\[ r = \frac{20}{2} = 10 \text{ cm} \]

  1. The height \( h \) of the cone is given as 15 cm.

  2. Using \( \pi = 3.14 \):

Now plug the values into the volume formula:

\[ V = \frac{1}{3} \times 3.14 \times (10)^2 \times 15 \] \[ V = \frac{1}{3} \times 3.14 \times 100 \times 15 \] \[ V = \frac{1}{3} \times 4710 \] \[ V = 1570 \text{ cubic centimeters} \]

So, the volume of the cone is 1,570 cubic centimeters.

The correct response is:

1,570 cubic centimeters.
