The death star ice mold is in the shape of a sphere, since it is round. The formula for the volume of a sphere is:
V = (4/3)πr³
where V is the volume and r is the radius of the sphere.
To find the radius of the death star ice mold, we need to divide the diameter by 2:
r = d/2 = 3/2 = 1.5 inches
Now we can substitute this value of r into the volume formula:
V = (4/3)π(1.5)³
= (4/3)π(3.375)
= 14.137 cubic inches
So the volume of one death star ice mold is approximately 14.137 cubic inches.
