GIven:
if 1 in³ = 0.55 oz
We are to find the formula for volume in fluid ounces where the dimensions are measured in inches.
First what we should know is that:
To convert a cubic measurement to a fluid ounce measurement, multiply the volume bt the conversion ratio. The volume in fluid ounces is equal to the cubic inches multiplied by 0.5541
So, the formula for the volume in fluid ounces where the dimension is measured in inches is:
V = 0.55 * πr²h
V = 0,55πr²h oz
Therefore the correct option is C.
