Let x be the amount (in oz) of pure silver used in this alloy. Each ounce of the pure silver contributes a value of $30.48, so that the total cost of the amount of pure silver that gets used is $30.48x.

The same goes for the secondary alloy, where each ounce costs $21.35, so that 52 ounces of the alloy contributes a total cost of $21.35*52.

The final alloy has a total mass of (x + 52) ounces, and each ounce costs $24.76, so that this alloy's totat cost is $24.76*(x + 52).

So we have

30.48x + 21.35*52 = 24.76*(x + 52)

30.48x + 1110.20 = 24.76x + 1287.52

5.72x = 177.32

=> x = 31

Using the illustration below, calculate the area of the circle.
Keith_Richards [23]
Find thy radius.

Thy radius is 7.25 (D / 2 = R)

Thy formula for area is A = (pi)r^2

Substitute and Solve

A = (pi)r^2
   = (pi)(7.25)^2
   = (pi)(52.5625)
   = 165.04625

Therefore, the area is about 165.

5).
and
6).
The volume of a sphere is

               (4/3) (pi) (radius)³ .

In #5, the 'pi' is already there next to the answer window.
You just have to come up with the (4/3)(radius³).

Remember that the radius = 1/2 of the diameter.

7).  The volume of a cylinder is

                         (pi) (radius²) (height) .

Divide the juice in the container by the volume of one can,
to get the number of cans he can fill.

8).  The volume of a cone is

                     (1/3) (pi) (radius of the round bottom)² (height) .

He starts with a small cone, he then adds clay to it to make it higher.
The question is:  How much clay does he ADD to the short one,
to make the bigger one ?

Use the formula to find the volume of the short one.
Use the formula again to find the volume of the bigger one.
Then SUBTRACT the smaller volume from the bigger volume.
THAT's how much clay he has to ADD.

Notice that the new built-up cone has the same radius
but more height than the first cone.
_______________________________________

Don't worry if you don't understand this.

The answer will be this number:

 (1/3) (pi) (radius²) (height of the big one minus height of the small one).
