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 con
ICE Princess25 [194]

Answer:

87.28 cubic inches

Step-by-step 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\frac{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(\frac{18.9}{3})

   = (27.783)π

   = 87.28 inch³

Conical mold can hold 87.28 inch³ candle wax.
