hii!!
here's ur answer..
given the diameter of the pipe is 1.4m.
therefore radius will be=1.4/2
=0.7m
and height (length) is 35m.
we have to find it's CSA as we have find the cost of painting.
CSA of the pipe=2πrh
=2×22/7×0.7×35
=44×0.7×5
=154m²
cost of painting if per m² costs ₹1.5=154×1.5
=₹231
hope this helps..!
