Question

the amount of cubic meters of water fill a pipe which is 3500m long and 0.08m in diameter is

Answer 1

Diameter of pipe = 0.08m
radius (r) = 0.08/2 = 0.04m
length(h) = 3500m
volume = πr²h = π×0.04²×3500 = 17.6 m³

So 17.6 m³ of water will the pipe.

Answer 2

hey ammu
here
h=3500m
r=0.04          (as our ravindar sir said)
here pipe will be a cylinder
volume of cuboid=$\pi r^{2} h$
=22/7*0.04*0.04*3500
=17.6
is it ok ani
