Here, height h = 7 m
radius (r) = 10 cm = 0.1 m
diameter (d) = 20 cm = 0.2m
apply formula of volume = π r^2 h
= 22/7 * 0.1 * 0.1 * 7
= 0.22 m^3
Weight of 1 cubic meter wood = 225kg/ m^3
That's why
225 * 0.22 = 49.5 kg .
It's our answer.
Hope it's useful.
All the best.

density = mass / volume ,
mass (kg) = density (kg / cm^3) * volume (cm^3)
mass (kg) = density (kg / cm^3) * volume (cm^3)
