Largest right circular cone cut out from cube
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.)
