Question

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)

Group of answer choices

16.75 cubic inches

20.93 cubic inches

24.25 cubic inches

33.49 cubic inches

Answer 1

A

Explanation:

Find the volume of both shapes.

Cylinder - V = πr²h = π·2²·4 = 50.26548

Sphere - V = 4/3πr³ = 4/3π·2³ = 33.51032

Find the difference between the two.

50.26548 - 33.51032 = 16.75516, or 16.75
