Question

The volume of cylinders iron rod of lengths 1 meter is 3850cm cube . Find it diameter

Answer 1

Step-by-step explanation:

Sol: Volume = 3850 cm3

Length i.e. height = 1 m = 100 cm Volume = πr2h 22/7 x r2 x 100

= 3850 r2

= 3850/100 x 7/22 r2

= 12.25 r2

= √12.25 r

= 3.5cm

So, the diameter of the rod is 2 x 3.5 i.e. 7 cm.
