Question

Leigh bought a conical candle wax mold. The height of the mold is 18.9 inches and the radius of the inside of the top of the conical

mold is 2.1 inches. She fills the mold completely with candle wax so that it is level with the top of the conical mold.

Answer 1

87.28 cubic inches

Explanation:

Leigh wants to fill the conical candle wax mold completely with candle wax.

We have to calculate the volume of the cone by the formula :

`V=\pi r^2(h)/(3)`

Here, V = volume

r = radius = 2.1 inches

h = height = 18.9 inches

By substituting these values given, into the formula

`V=\pi (2.1)^2((18.9)/(3))`

= (27.783)π

= 87.28 inch³

Conical mold can hold 87.28 inch³ candle wax.
