Asolid gold cube with edge of 2" is melted down and recast as a cone with a 3" radius base. find the height of the cone. 8/(9) 2 8/(3)

The height of the cone is

Step-by-step explanation:

step 1

Find the volume of the cube

The volume of a cube is equal to

where

b is the length side of the cube

we have

substitute

step 2

Find the height of the cone

The volume of the cone is equal to

we have

-----> the volume of the cone is equal to the volume of the cube

substitute the values and solve for h

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

its a, i had the same answer, its from study island right
