Question

an iron poleis 4m high and 28 CM in diameter find its weight if the iron weight if the iron weighs 50kg per m sq​

Answer 1

So as here, Radius = 28/2 = 14 cm = 14/100 = 0.14 mtrs

Height = 4 m

VOLUME OF THE POLE = pi r^2 h

Volume = 22/7 * 0.14 * 0.14 * 4

Volume = 22 * 0.02 * 0.14 *4 = 0.2464 m^3

thus the Volume is = 0.2464 m^3

Volume × per unit weight

Weight = 0.2464 * 50 = 12.32 kg
