# Largest right circular cone cut out from cube

The volume, in cm³, of the largest right circular cone that can be cut out of a cube of side 9 cm is approximately

- 243
- 382
- 573
- 191

**Answer : (4). 191**

We have a cube having each is 9cm.

Then , a right circular cone is cut from it Cone having dimension are ; **radius of cone = 4.5cm, height of cone = 9cm.**

As, we know that the formula for finding Volume of cone

** volume of Cone = ( pie * r2 *h ) * 1 / 3**

** volume of Cone = 0.33 * 3.14 *( 4.5 * 4.5 * 9 )**

** volume of Cone = 1.04 * 20.25 * 9.42**

** volume of Cone = 9.42 * 20.25**

** volume of Cone = 190.755 **

On rounding off volume is** 190.755 ~ 191cm3.****(approx.)**
