The weight of a metal sphere was measured to be 9.81 g. Unfortunately, the caliper that was supposed to be used in measuring the dimensions of the sphere broke. The metal that make up the sphere was identified to be an alloy of iron and chromium with a density of 7.26 g/cm3. Using the data given, calculate the radius of the metal sphere in cm. Round your answer to 2 decimal places.
