If the exercise ball has been filled with Nitrogen which has a density of 0.2 grams per cubic inches. Find the mass in grams.
Jobisdone [24]

Answer:

m = 11581.2 grams

Step-by-step explanation:

Given that,

The density of the ball, d = 0.2 g/in³

The radius of the ball, r = 24 inches

We need to find the mass of the ball in grams.

The density of an object is hiven by :

d=\dfrac{m}{V}\\\\d=\dfrac{m}{\dfrac{4}{3}\pi r^3}\\\\m=\dfrac{4}{3}\pi r^3\times d

Put all the values,

m=\dfrac{4}{3}\pi \times 24^3\times 0.2\\\\m=11581.16\ g

or

m = 11581.2 grams

Hence, the mass of the ball is 11581.2 grams.
