Question

A cylindrical metallic pole has a diameter 48cm and height2.1m if 1 m cube of metal weighs 240kg find its weight

Answer 1

Answer:

921984

Step-by-step explanation:

volume of cylinder is $\pi rx^{2} h$

hence volume of cylinder is 3841.6$m^{3}$

volume of cube is $1 m^{3}$

hence $1 m^{3}$ = 240 Kg

this means :-

3841.6$m^{3}$ = 9841.6 * 240 Kg = 921984 Kg
