Question

A candle maker uses a mold to make candles like

the one shown below.

The height of the candle is 13 cm and the
circumference of the candle at its widest measure is
31.416 cm. Use modeling to approximate how
much wax, to the nearest cubic centimeter, is
needed to make this candle.

Answer 1

Answer: 340 cm3

Explanation:

Hi, to answer this question we have to apply the next formulas:

Circumference = 2π radius

Replacing with the circumference value and solving for r:

31.416 =2π r

31.416 /2π =r

5cm =r

And then:

Volume of a cone = 1/3 x π x radius^2 x height

Replacing with the values given:

V = 1/3 π (5)^2 (13) = 340 cm3
