Question

The volume of a circular pipe of length 2m is 1078cm find its diameter

Answer 1

Answer:

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

r = √12.25

r = 3.5

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