Question

HURRY PLZZZZ!!!! The density of water is 1 gram per cubic centimeter. A more dense object will sink, and a less dense object will float. Will a marble with a radius of 1.4 cm and a mass of 9 grams sink or float in water? The marble will because the density of the marble is about grams per cubic centimeter.

Answer 1

Answer:

float

Step-by-step explanation:

Density  = mass divided by volume

Volume of sphere = 4/3 * pi * r^3

Volume of sphere = 4/3 * pi * 1.4^3

Volume of sphere = 11.49

Density  = mass divided by volume

Density  = 9/11.49

Density  = .78

since .78 is less than 1 it will float

Answer 2

Answer:

float, 0.78
