​

Answer 1

Answer:

a cyclindrical rod of sliver has a length of 0.7 m and a radius of 0.4m

Answer 2

Solution :-

Given ,

• Length or height of rod = 0.7m
• Radius of rod = 0.4 m
• Mass of rod = 3700 kg

We need to find ,

• Density of silver rod

If we need to find the density of silver rod firstly we need to find the volum of rod . Since the rod is in cylindrical shape .

• Volume = πr²h

→ Volume ( rod ) = π × ( 0.4 )² × ( 0.7 )

→ Volume ( rod ) = 3.14 × 0.16 × 0.7

→ Volume of rod = 0.351 m³

Now , finding density of rod using ,

• Density = mass/volume

⇒ Density = 3700/0.351

⇒ Density = 10541.31 kg/m³

Hence , density of silver rod is 10541 kg/m³
