:the mass of a ball is 128 g. it has a density of 0.5 g/cm³. what is the volume of the ball? show your work and place a box around your answer. optional bonus point: what is the radius of the ball?

Part 1) The volume of the ball is 256 cm³

Part 2) The radius of the ball is 3.94 cm

Step-by-step explanation:

Part 1) we know that

The density is equal to divide the mass by the volume

D=m/V

Solve for the volume

The volume is equal to divide the mass by the density

V=m/D

In this problem we have

m=128 g

D=0.5 g/cm³

substitute

V=128/0.5=256 cm³

Part 2) what is the radius of the ball?

we know that

The volume of the sphere (ball) is equal to

we have

assume

substitute and solve for r
