Example Question - volume of cone calculation

Calculating the Volume of a Cone

The volume of a cone can be calculated using the formula: \[ \text{Volume} = \frac{1}{3} \pi r^2 h \] Where \( r \) is the radius of the base of the cone and \( h \) is the height of the cone. For a cone with a height \( h = 20 \) cm and a base radius \( r = 10 \) cm, we can plug these values into the formula to get the volume: \[ \text{Volume} = \frac{1}{3} \pi \times (10 \text{ cm})^2 \times 20 \text{ cm} \] The correct formula to use for the calculation, based on the given information and the options provided in the image, is the third one: \[ \boxed{\frac{1}{3} \pi \times (10 \times 10) \times 20} \]
