Question

A ball with radius = 80cm, and mass = 18Kg. What is its density in g/cm3? Round to appropriate significant figure.

Answer 1

I assume the ball is in the shape of a sphere.
Find the volume in cm^3 of a sphere with radius 80 cm.
Then convert the mass from kg to g.
Then divide the mass in grams by the volume in cm^3.

Answer 2

voume is 2.14466×106

Answer 4

Correct. That is in cm^3.
Now convert 18 kg into grams.
Then divide the mass in grams by the volume in cm^3.
