Find the volume of largest right circular cone that can be cut out from a cube of edge 4.2 cm |
|
Answer» r=2.1 h=4.2 v=1/3πr²h .....v=1/3*22/7*2.1*2.1*4.2=19.404 The volume of the largest right circular cone that can be cut out from a cube of edge 4.2 cm is 19.404 cm^3.Solution:Edge of the cube = 4.2 cmi.e 2r = 4.2r = 4.2/2 = 2.1 cmh = 4.2 cmVolume of the cone = 1/3 * pi * r^2 * h=> 1/3 * 22/7 * 2.1 * 2.1 * 4.2=> 19.404 cm^3Hence, the volume of the largest right circular cone that can be cut out from a cube of edge 4.2 cm is 19.404 cm^3. But how 19.404 19.04cm3 |
