Question

the largest position right circular cone is cut out of a cube of side edge r centimetre what is the volume of cone?

Answer 1

Step-by-step explanation:

h = r (depth of the cube)

radius = half of r  ,   since the side of the cube will be the diameter of the cone

vol of cone = 1/3(pi x r^2 x h)

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

=1/3(pi x r^2/4 x r)

=1/3(pi x r^3/4)

=1/12(pi x r^3) cm^3
