Question

find the volume of the largest right circular cone that can be cut out of a cube whose edge is 7 cm​

Answer 1

Answer:

volume will be 89.8333cm^{3}

Step-by-step explanation:

the largest cone cut out will have ,

radius of 3.5 cm and height of 7 cm

$volume = \frac{1}{3}\pi  r^{2}  h$$volume = \frac{1}{3} \frac{22}{7} (3.5)(3.5)(7)\\volume = \frac{ 22(12.25)}{3} \\\\volume= 89.833333 cm^{3}$

Answer 2

Given

Height of cone=7cm radius of base of cone=7/2 volume of cone=1/3πr2=1/3×22/7×7/2×7/2×7=11×49/6=89.83
