Please help will fan and medal Question and Picture in description

Answer 1

Sean used candle molds, as shown, to make candles that were perfect cylinders and spheres:

A cylindrical mold is shown, the radius of the top circular section of the cylinder is labeled 3 inches and the height of the cylinder is labeled as 6 inches. On the right side of this mold is a spherical mold. The radius of this spherical mold is labeled as 3 inches.

What is the approximate difference in the amount of wax needed to make a candle from each of these molds? Use π = 3.14.

18.0 cubic inches
28.26 cubic inches
37.0 cubic inches
56.52 cubic inches

Answer 2

Uses the formulas for volume:
Sphere = (4/3) * pi * radius^3
Cylinder = pi * radius^2 * height

What has you confused? I'd be glad to help

Answer 6

well i dont understand how to get the answer

Answer 7

Okay, lets break this question down. The problem asks you to find the difference in the amount of wax needed to make two candles. So right here since we need the amount of wax we know we will be finding volume. Since it asks for the difference we know we will be subtracting at least two volumes from each other.

So to find the volumes we have the equations I mentioned above.
All of the values we need are mentioned in the information of the problem.

For the cylinder the problem tells us the radius is 3 inches, and the height is 6 inches.
So plugging that into the equation we get (3^2)*pi*6 (i dont have a calculator in front of me, but this should be near 162)

Doing the same thing with the sphere, using the radius stated in the problem we get the equation (4/3)*(3^3)*pi

Now you have the amount of wax needed to make each candle. Finding the difference is simply subtracting the two values
