The height of the described cylinder is 0.85 cm

Mass= 98g

Density= 8.9g/cm^3

Density= (mass/volume)

Substitute the values

8.94= 98/ volume

Volume= $\frac{98}{8.94}$

Volume= 10.97 $cm^{3}$

Volume of a cylinder can be found with (V = π r 2 h.)

h= height of cylinder ?

radius= 2cm

Substitute the values

10.97= π × $2^{2}$ × h

h= 10.97/12.57

h= 0.85 cm

Therefore, height of the described cylinder is 0.85 cm
