You are filling paper cones with popcorn for a party.

Sunny_sXe [5.5K]

Answer:

The amount of popcorn needed to fill the paper cone is $V=1,005\ cm^{3}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

In this problem we have

$r=8\ cm$

$h=15\ cm$

$\pi =3.14$

substitute

$V=\frac{1}{3}(3.14)(8)^{2}(15)$

$V=1,005\ cm^{3}$
