Question

If a cone of height 7 m and base radius 35 m is melted and recast to a cylinder having base diameter 35 cm find the length of the cylinder

Answer 1

vol. of cone = 1/3*π*^2*h

=1/3*22/7*35*35*7

=8983.33

vol. of cylinder = π*r^2*h

=22/7*6.5*6.5*h

=132.78*h

vol. of cone = vol. of cylinder

8983.33 = 132.78*h

h= 8983.33/132.78

h= 67.65
