I hope this helps you

n=360/exterior angle

10=360/exterior angle

exterior angle=36

36+interior angle=180

interior angle=144

Answer:

$2.3\:\mathrm{in^3},\\1.3\:\mathrm{fl\:oz}$

Step-by-step explanation:

The volume of a cone with radius $r$ and height $h$ is equal to $V=\frac{1}{3}\cdot r^2\pi\cdot h$ .

What we're given:

Since radius is half the diameter, $r$ is $1.1$
Height of $1.8$

Substituting given values, we get:

$V=\frac{1}{3}\cdot 1.1^2\pi \cdot 1.8=0.726\pi\approx \boxed{2.3\:\mathrm{in^3}}$

Convert to fluid ounces using the conversion given in the question:

$0.726\pi}\cdot \frac{0.554}{1}\approx \boxed{{1.3\:\mathrm{fl\:oz.}}}$
