The candle company is designing a new cylindrical candle. they are looking at for different molds. which mold will use the least amount of wax? hurry im timed

Mold b will use the least amount of wax.

Step-by-step explanation:

The formula for volume is :

Mold A :

r = 1 in

h = 7 in

V = cubic inches

Mold B :

r = 1 in

h = 4 in

V = cubic inches

Mold C :

r = 1.5 in

h = 3 in

V = cubic inches

Mold D :

r = 2 in

h = 3 in

V = 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.

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
