Question

An iron pole is 4 m high and 28 cm in diameter. Find its weight if the iron weigh 5g per m³

Answer 1

Step-by-step explanation:

h=4 (1m=100cm) 4m=400cm

r=28cm

volume of cylinder= πr^2h

=22/7×28×28×4.

=22×4×28× 4

=22×28×4×400

=22×28×1600

=985600cm^3

=9856m^3

1m^3=5g

9856m^3=?

49280g
