Answer:
A.) 16.75
Step-by-step explanation:
First, find the volume of each mold:
[tex]Cylinder_{volume}[/tex] = πr²h
Where,
π = 3.14
r = 2 in
h = 4 in
[tex]Cylinder_{volume} = 3.14*2^2*4 = 50.24 in^3[/tex]
[tex]Sphere_{volume}[/tex] = ⁴/3πr³
Where,
π = 3.14
r = 2 in
[tex]Sphere_{volume} = \frac{4}{3}*3.14*2^3 = 33.49 in^2[/tex]
Approximate difference in the amount of wax needed = 50.24 - 33.49 = 16.75 in^3
