Question

Please help me to solve ​

Answer 1

Answer:

he height of the cone so formed=the height of the cube i.e.its side.

its diameter=the base side=its other sides.

so the height and diameter of the cone= the side of the cube from which it is cutout.

radius=side by 2,let side be 'r' then:

the vol.of cone=1/3 pi r^2 h,

=1/3*pi*(r/2)^2*r

=1/3*pi*r^2/4*r

=1/12 pi r^3
