Bill 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 2 inches and the height of the cylinder is labeled as 5 inches. on the right side of this mold is a spherical mold. the radius of this spherical mold is labeled as 2 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. 20.82 cubic inches 29.31 cubic inches 56.6 cubic inches 62.8 cubic inches

29.31

Step-by-step explanation:

29.31 cubic inches

Step-by-step explanation:

The dimension of the cylindrical mold is:

Radius (r) = 2 inches

Height of the cylinder (h)= 5 inches

The dimension of the sphere is:

Radius (r) = 2 inches

Lets calculate the amount of wax needed for the cylindrical candle:

A

cubic inches

Now, lets calculate the amount of wax needed for the spherical mold:

cubic inches

So the approximate difference in the amount of wax needed to make a candle from each of these molds is given by:

Amount of wax for the spherical mold subtracted by the amount of wax for cylindrical mold:

cubic inches

So the approximate difference in the amount of wax is 29.31 cubic inches.

is their an equation anywhere i can take a   look at it and see if i am right.
