By melting a solid cylindrical metal,a few conical materials are to be made. If three times the radius of the cone is equal to twice the radius of the cylinder and the ratio of the height of the cylinder and the height of the cone is 4:3, find the number of cones which can be made

A cylindrical container is to be made from certain solid material with the following constraints: It has a fixed inner volume of V mm^3 , has a 2 mm thick solid wall and is open at the top. The bottom of the container is a solid circular disc of thickness 2 mm and is of radius equal to the outer radius of the container. If the volume of the material used to make the container is minimum when the inner radius of the container is 10 mm, then the value of V/(250 pi) is

A cylindrical container is to be made from certain solid material with the following constraints : It has a fixed inner volume of V "mm"^(3) , has a 2 mm thick solid wall andis open at the top. The bottom of the container is a solid circular disc of thickness 2 mm and is of radius equal to the outer radius of the container. If the volume of the material used to make the container is minimum when the inner radius of the container is 10 mm, then the value of (V)/(250pi) is-
