Question

The height of a solid cylinder is 10.5 cm. If its volume is 2112 cm^3.find the radius of the cylinder

Answer 1

H = 10.5 cm
Volume = 2112 cm3
As we know that,
Volume of cylinder = pie x r2 x H
2112= r2 x 33
r2=64
r=8 cm

Answer 2

The height of the solid cylinder is 6.09 cm.

Step-by-step explanation:

Given : The height of a solid cylinder is 10.5 cm. If its volume is 2112 cm³.

To find : The radius of the cylinder ?

Solution :

The volume of the cylinder is given by,

$V=\pi r^2 h$

Where, V is the volume V=2112 cm³

r is the radius r=10.5 cm

h is the height

Substitute in the formula,

$2112=\frac{22}{7}\times (10.5)^2\times h$

$h=\frac{2112\times 7}{22\times 10.5\times 10.5}$

$h=6.09\ cm$

Therefore, the height of the solid cylinder is 6.09 cm.
