Answer:
Step-by-step explanation:
Volume of the pole = 22/7 x 0.1 x 7
= 2.2mcube
Weight of the pole = 225x2.2
= 495kg
Therefore the weight of the pole is 495kg
Answer:
49.5kg
Step-by-step explanation:
Given---> Height of pole = 7m
Diameter of pole = 20cm
Weight of wood per m³ = 225 kg
Solution---> ATQ,
Height of pole = 7m
Diameter of pole = 20cm
Radius of pole = diameter of pole / 2
= 20 / 2 = 10 cm
= 10 / 100 = 0.1 m
Volume of cylinder = π r² h
= ( 22/7 ) × ( 0.1 )² × 7
= ( 22 ) × ( 0.01 )
= 0.22 m³
ATQ, weight per m³ = 225 kg
So, weight of pole = 225 × 0.22
= 49.5 kg
