Question

what is the volume of the largest circular cone that can be cut out from a cube of edge 8.4cm?

Answer 1

↑ Here is your answer ↓
_____________________________________________________________
_____________________________________________________________

Info we have,

$h = 8.4 cm$

$r = 4.2 cm$

Volume of cone,

$1/3 \pi r^2 h$

$1/3 * 22/7 * 4.2 * 4.2 * 8.4$

$= 155.232 cm^3$

Answer 2

Volume of the largest cone = Volume of the cone with diameter of base 8.4 and height 8.4 cm

Volume of cone=1/3πr²h
=> 1/3×22/7×4.2×4.2×8.4=155.232cm³



Note: radius is taken as 4.2cm, as diameter is 8.4 cm
