Density = Mass / Volume
10.5 = 500 / x
10.5x = 500
x = 50 cm^3 (1 sig fig) volume of the sphere
Volume of a sphere = 4/3 pi r^2
pi = 3.14 r = radius
50 = 4/3 pi r^3
50•3/4 = pi r^3
37.5 = pi r^3
37.5/pi = r^3
11.9 = r^3
cube root(11.9) = r
2.3 = r
Diameter = 2•radius
Diameter = 2 • 2.3
Diameter = 5 cm (1 sig fig) diameter

Particle accelerators is your answer
density is the mass of an object/ liquid per unit volume
formula for density is as follows
density = mass / volume
the mass of steel is 80 g
and density is 8 g/cm³
substituting the values in the equation we can find the volume
volume = 80 g/cm³ / 8 g
volume = 10 cm³
volume of the sample is 10 cm³
