You divide 162 and it equals to 81
A. Both triangles equal 50 and 10x5 is 50. Therefore, y=5.
It is

The equation for area of a trapezoid is

Substituting our values in

We can then simplify the expression

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.
