Question

The volume of a right circular cone, with a base radius the same as its altitude, and the volume of a hemisphere are equal. The ratio of the radii of the cone to the hemisphere is:

solve fndz correctly....

Answer 1

Dear Student:

  Volume of cone(V) =

Where,   r is the radius of cone

              h is the altitude

                           r=h/2

                           h=2r

                           V=

                           V=

Volume of hemisphere(U)=

Where,a is the radius of hemisphere.

                            V=U

Hence,       r=a

So,  r/a=1
