Question

A wooden pole is 7 m high and 20 cm in diameter. Find its weight if the wood weighs 225kg per meter cube​

Answer 1

Step-by-step explanation:

It is given in the question that,

Radius of the cylindrical pole (r) = 10cm = 0.1m

Height of the cylindrical pole (h) = 7m

Now,

Volume of the cylindrical wooden pole =

= πr^2h

= π* (0.1) *7

= 0.22 cm3

Now,

We know that,

Weight of the wood = 225 kg/m3

∴ Weight of the pole = 0.22× 225

= 49.5 kg
