Gold in the form of solid cylinders will be molded into solid blocks. Each cylinder has a diameter of 6.18 cm and a height of 6
nordsb [41]

First we need to find out the volume of one cylinder. We already know the volume of the block of gold is 360cm3

V = Pie * radius squared* height.

Pie is 3.142

radius is 6.18/2 = 3.09 cm

height is 6cm

V = 3.142 * 3.09 * 3.09 * 6

V = 180cm3

Now we divide the volume of this cylinder with the volume of block of gold.

360/180 = 2

So it will take 2 cylinders to mold one block of gold.

You will need 8 drops of blue coloring to mix icing with 4 drops of yellow coloring.

In order to make the icing, you <u>used 2 drops of yellow coloring</u> for every<u> 4 drops of blue coloring. </u>

You need to first find the unit rate of blue coloring to yellow coloring.

<em>= blue coloring required / yellow coloring </em>

= 4 / 2

= 2

This means that for every drop of yellow coloring used, 2 drops of blue is used.

If you are to <u>use 4 drops of yellow</u>, the number of blue drops to use is:

<em>= Number of yellow drops x unit rate</em>

= 4 x 2

= 8 drops of blue coloring

In conclusion, you will need 8 drops of blue coloring for 4 drops of yellow coloring.
