Question

14. A wooden pole is 7 m high and 20 cm in diameter. Find its weight iſ the wood weight if the wood weighs 225 kg m³​

Answer 1

Answer:

hy

Step-by-step explanation:

length of pole is 7m

and diameter of pole = 20cm = 0.2 m

so, the radius of pole = 0.1m

now, volume of pole = volume of cylinder = πr²h

= 22/7 × 0.1 × 0.1 × 7

= 22 × 0.01

= 0.22 m²

now, weight = volume × density

here given,

density = 225 Kg/m³

volume of pole = 0.22 m³

now, weight = 225 × 0.22

= 49.5 Kg

hence, weight of pole = 49.5 Kg

Answer:

49.5 kg
