To find the volume of the cone, we first need to gather the dimensions:

  1. Diameter of the cone = 30 cm
  2. Radius (r) = Diameter / 2 = 30 cm / 2 = 15 cm
  3. Height (h) = 2 × Diameter = 2 × 30 cm = 60 cm

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

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

Now, substituting the values into the formula:

\[ V = \frac{1}{3} \pi (15 \text{ cm})^2 (60 \text{ cm}) \]

Calculating \( (15 \text{ cm})^2 \):

\[ (15 \text{ cm})^2 = 225 \text{ cm}^2 \]

Now substituting this back into the volume formula:

\[ V = \frac{1}{3} \pi (225 \text{ cm}^2)(60 \text{ cm}) \]

Calculating the product:

\[ 225 \times 60 = 13500 \]

Now plug this back into the volume equation:

\[ V = \frac{1}{3} \pi (13500 \text{ cm}^3) \]

Calculating \( \frac{13500}{3} \):

\[ \frac{13500}{3} = 4500 \]

Thus, we have:

\[ V = 4500 \pi \text{ cm}^3 \]

So, the volume of the cone is:

4,500π cm³

The correct response is:

4,500π cm3
