Volume of a cylinder and radius

AI Thread Summary
To calculate the radius of a cylinder, the volume must be converted into cubic inches if the desired radius is in inches. Using consistent units is crucial for accurate dimensional analysis. If the volume is initially in imperial fluid ounces, it should be converted to cubic inches to maintain unit compatibility. The cylinder's length should already be in inches for proper calculations. Consistent unit usage simplifies the process and avoids confusion.

Ok so i know the equation for the volume of a cylinder and the equation for calculating the radius. But when calculating the radius does the volume need to be converted into cubic inches or can it stay as imperial fluid ounces.
Thanks

It needs to be converted into cubic inches first if you want the radius in inches.
 
Use the volume units that are needed. Convert the length units to inch equivalents or convert the length units to their imperial fluid ounce unit.
Looking at what you described, you want a radius value, and you have the volume and cylinder length. Convert the volume into cubic inches! Now you have a formula for radius in inches. Your cylinder length should already be in inches.

Sigh. See what happens when people do not use SI units! The dimensional analysis gets very complicated (and when people skip that part, the answer makes no sense).
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
