A magic 8 ball has a diameter of 5 inches. It is filled 85% full with bull water. How much space is occuppied by water? Round to the nearest tenth?

Sagot :

Using the volume of the sphere, it is found that 445.1 in³ of the ball is occupied by water.

What is the volume of a sphere?

The volume of a sphere of radius r is given by:

[tex]V = \frac{4\pi}{3}r^3[/tex]

In this problem, the radius is of r = 5 in, hence the volume in cubic inches is given by:

[tex]V = \frac{4\pi}{3}(5)^3 = 523.6[/tex]

85% of this is filled by water, hence the space occupied by water, in cubic inches, is of:

0.85 x 523.6 = 445.1.
