What is the volume of a cone with a radius of 6cm and a height of 11 cm?

Hint: You may want to use your calculator to help complete the math for this problem, but you will also need the formula for the Volume (V) of a cone. That formula is V = (π)(r²)(h/3).

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

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

Where:

  • \( r \) is the radius,
  • \( h \) is the height, and
  • \( \pi \) is approximately \( 3.14 \).

Given:

  • \( r = 6 \) cm
  • \( h = 11 \) cm

First, calculate \( r^2 \): \[ r^2 = 6^2 = 36 \]

Now, substitute the values into the formula: \[ V = \frac{1}{3} \pi (36)(11) \]

Calculating the product of \( 36 \) and \( 11 \): \[ 36 \times 11 = 396 \]

Now substitute this back into the volume formula: \[ V = \frac{1}{3} \pi (396) \]

Calculating \(\frac{1}{3} \times 396\): \[ \frac{396}{3} = 132 \]

Now multiply by \( \pi \): \[ V \approx 132 \times 3.14 \approx 414.48 \text{ cubic centimeters} \]

Therefore, the volume of the cone is approximately 414.48 cubic centimeters.

The correct response is: 414.48 cubic centimeters.
