Gary used candle molds, as shown below, 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. A.) 16.75 cubic inches B.) 20.93 cubic inches C.) 24.25 cubic inches D.) 33.49 cubic inches

A.) 16.75

Step-by-step 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

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
