Question

a wooden cylindrical pole is 7 m high and base radius is 10 cm find its weight if the
wood weights 225 kg per cubic metre

Answer 1

Answer:

volume if cylinder is pi*r^2*h

so volume is 2200 cubic metres

weight is equal to 225*2200= 495000kg

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation :

We have to calculate the volume of cylinder..

So the volume of cylinder is pie r^2 h

Putting the values:

22/7 × 10 × 10 × 7 × 100

= 22 × 100 × 100

= 220000 cm^3 = 2200m^3

The weight will be:

1 m^3 is 225kg so 2200 m^3 will be

2200 × 225 = 495000kg.
