In a workshop, you need to fill a cylindrical tank with a liquid. The tank has a diameter of 1 meter and a height of 2 meters. Which method will give you the most accurate measurement of the tank's volume before filling it?
Calculate using the formula for the volume of a cylinder based on precise measurements
The accuracy of a volume calculation depends on using the formula that matches the true geometric shape of the container being measured.
The tank described is a cylinder, so its volume must be found with the cylinder formula, which relates volume to the base area and the height.
That formula is \(V=\pi r^2 h\), where the radius comes from the 1 metre diameter and \(h\) is the 2 metre height, both taken by careful measurement.
Applying it with precise measurements of diameter and height reproduces the tank's real capacity before any liquid is poured.
Using the cube formula assumes flat square sides the tank does not have, so it badly overstates the volume.
Treating it as a sphere assumes the wrong solid entirely, and judging by eye is only a rough guess, so all three give inaccurate results.
Hence, the answer is Calculate using the formula for the volume of a cylinder based on precise measurements.
