Question

I HAVE 10 MINUTES PLEASE HELP!!!!The density of water is 1 gram per cubic centimeter. An object floats in the water if its density is less than water's density, and it sinks if its density is great than water's.

Suppose a ball with mass 90 grams is in the shape of a sphere with radius 4 centimeters. Will the ball sink or float in the water?

The volume of the ball is about___cubic centimeters. The density of the ball is___grams per cubic centimeter. Based on its density, the ball will___.

Answer 1

The base should be sink

Calculation of the volume, density:

Since the density of water is 1 gram per cm^3.

The volume is

Here a = base area and h = height of the pyramid

So,

Now

Density is

Since The mass of the pyramid is 1.17 g.

So, the density is

Density

Since its density is more than that of water, so it will sink.

Hence, we can conclude that The base should be sink.

Explanation:

Hope this helped!

Answer 2

Explanation:

Basically, we want to use the formula for the area of a sphere: V = 4/3πr^3

And plug-in our radius, 4 for r.

We get an answer around 67 sooooooo

The volume of the ball is about__67__cubic centimeters. The density of the ball is__1.343__grams per cubic centimeter. Based on its density, the ball will__sink__.
