The mass of the copper cylinder is 177065.856g
Given:
Radius of the copper cylinder R=12cm
Height of the copper cylinder H=44cm
Density of the cylinder=8.90
To find:
Mass of the copper cylinder
<u>Step by Step by explanation:</u>
Solution:
According to the formula, Mass can be calculated as
and from this
Where, m=mass of the cylinder
=density of the cylinder
v=volume of the cylinder
And also cylinder is provided with radius and height value.
So volume of the cylinder is calculated as
Where =3.14
r=radius of the cylinder=12cm
h=height of the cylinder=44cm
Thus,
v=3.14 \times 144 \times 44
And we know that,
Substitute the known values in the above equation we get
m=177065.856g or 177.065kg
Result:
Thus the mass of the copper cylinder is 177065.856g
