1.	What is the density of a sphere that has a radius of 6 cm and a mass of 100 g
Answer» ANSWER: The DEFINITION of density of a body is MASS of the body per unit volume of the body. From this we get Density = Mass/Volume. In the above problem, We have 2 things: Mass of the sphere is 100 g and Radius of the sphere is 3 centimeter. Thus we have to find the volume of the sphere. The formula for finding the volume of a sphere is: 4/3piRrr( Here r stands for radius..we find r to the power 3) If u do math here, the vol. of the sphere is 113.1 cm 3 . So we have the mass and volume of the sphere. That’s all that we need. Just plug in the values: Density= 100/113.1 g/cm 3 . If you do the math here, you get the value of density of the sphere as 0.8841 g/cm 3 .

Answer»

The DEFINITION of density of a body is MASS of the body per unit volume of the body. From this we get Density = Mass/Volume.

In the above problem, We have 2 things: Mass of the sphere is 100 g and Radius of the sphere is 3 centimeter.

Thus we have to find the volume of the sphere.

The formula for finding the volume of a sphere is:

4/3*pi*R*r*r( Here r stands for radius..we find r to the power 3)

If u do math here, the vol. of the sphere is 113.1 cm 3 .

So we have the mass and volume of the sphere. That’s all that we need. Just plug in the values: Density= 100/113.1 g/cm 3 .

If you do the math here, you get the value of density of the sphere as 0.8841 g/cm 3 .
