Question

the volume of a circular iron rod of length is 1m 3850 cm³ . find its diameteroķ​

Answer 1

Answer:

Diameter=7cm

Step-by-step explanation:

Given volume of circular iron rod is 3850 cm

3

But we know that Volume of cylinder =πr2h

3850=22/7×r×r×100 [as length 1 m=100 cm

r

2

=(3850×7)/(100×22)

r=1.75×7

r=3.5 cm

Therefore diameter =2×r

Diameter =2×3.5=7 cm
