Question

A solid cylindrical in shape has length 19cm and radius 5cm. It weighs 7500g calculate its density .

Answer 1

Solution:-

Given:-

• Height of Cylinder = 19cm
• Radius of Cylinder = 5cm
• Mass/Weight of Cylinder = 7500g

To Find:-

• Density of Cylinder = ?

Find:-

Volume of Cylinder = πr²h

=) Volume = (22/7) × 5 × 5 × 19

=) Volume = 3.14 × 25 × 19

=) Volume = 1491.5 cm³

Hence,

• Volume of Cylinder is 1491.5 cm³

We know that,

Density = Mass/Volume

=) D = (7500/1491.5) cm³/g

=) D = 5.02 cm³/g

Hence,

• The Density of Cylinder is 5.02 cm³/g.
