Question

Gary used candle molds, as shown, to make candles that were perfect cylinders and spheres:What is the approximate difference in the amount of wax needed to make a candle from each of these molds? Use π = 3.14.

Answer 1

Answer: A) 16.75 cubic inches.

Explanation:

First, find the volume of each mold:

= πr²h

Where,

π = 3.14

r = 2 in

h = 4 in

= ⁴/3πr³

Where,

π = 3.14

r = 2 in

Approximate difference in the amount of wax needed = 50.24 - 33.49 = 16.75 in^3
