Answer 1

Answer: Option B

(B) Mold B

Explanation:

Answer 2

Mold b will use the least amount of wax.

Explanation:

The formula for volume is :
`v=\pi r^(2) h`

Mold A :

r = 1 in

h = 7 in

V =
`3.14*1*1*7=21.98` cubic inches

Mold B :

r = 1 in

h = 4 in

V =
`3.14*1*1*4=12.56` cubic inches

Mold C :

r = 1.5 in

h = 3 in

V =
`3.14*1.5*1.5*3=21.195` cubic inches

Mold D :

r = 2 in

h = 3 in

V =
`3.14*2*2*3=37.68` cubic inches

Now comparing the volumes of all the molds, we can see that the volume of mold B is the least. This means it will use the least amount of wax.
