Question

A solid metal cylinder of height and diameter is melted and recast into two cones in the proportion of (volume), keeping the height what would be the value of if ratio of total surface area of both cone is ? Options 1 7 2 9 3 5 4 15

Answer 1

Answer:

Step-by-step explanation:

Let radius of cylinder, cone 1, cone 2 = R, r1, r2 respectively.

Let their volumes be V, v1, v2 respectively.

Cylinder is melted and recast into cone 1 & cone 2

So V = v1 + v2.

Ratio of volumes of the two cones v1 : v2 is 3 : 4.

If v1 is 3x, v2 will be 4x

Hence, volume of cylinder V= 7x
