Question
The diameter of a metallic ball is 4.2 cm. What is the mass of the ball , if the density of the metal is 8.9 g per cubic cm ?
Hint:
We have given diameter of metallic ball .and the density of the metal is
We have to find the mass of the ball.
The correct answer is: = 2762.5511gm
Step 1 of 1:
We will first find the volume of the metallic ball
Now we know that
Density = 
Put the value of density and volume in formula, we will get mass
Density =
8.9 = 
Mass = 8.9 
310.399gm
= 2762.5511gm
