What is the exact volume of a sphere with a diameter of 36 in.?

Contact [7]

The volume of a sphere:
$V=\frac{4}{3} \pi r^3$
r - the radius

The diameter is twice the radius.
$d=36 \ in \\
r=\frac{36}{2} \ in = 18 \ in \\ \\
V=\frac{4}{3} \pi \times 18^3=\frac{4}{3}\pi \times 5832=\frac{23328}{3} \pi=7776\pi \ [in^3]$

The exact volume of the sphere is 7776π in³.

Katen [24]

$3 \frac{1}{2} = \frac{7}{2}$

$\frac{7}{2} \times 8 = 28$

$\frac{28}{12} = \frac{14}{6} = \frac{7}{3} = 2 \frac{1}{3}$

So each hiker gets 2 1/3 cup of trail mix.
