Gary 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 4 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. (5 points)


16.75 cubic inches

20.93 cubic inches

24.25 cubic inches

33.49 cubic inches

Answer:

a) 16.75 cubic inches  

Step-by-step explanation:

Cylindrical mold:  

   V = πr²h

where V is volume, r is radius, and h is height.  

Substituting the known values:

    V = π(2 in)²(4 in)

    V = 16π in³ = 50.26 in³

Spherical mold:

   V = 4πr³/3

Substituting the radius to the equation,

   V = 4π(2 in)³ / 3  

   V = 32π/3 in³ = 33.51 in³

The difference is calculated below:

D = 50.26 in³ - 33.51 in³

D = 16.76 in³
