A right curcular cylindrical tunnel of diameter 2 m and length 40 m is to be constructed from a sheet of iron. The area of the iron sheet required in m 2 , is

Question

Philoid · Accepted Answer

Given,

Diameter of cylindrical tunnel = 2 m

So radius =

Length of tunnel = 40 m

Area of iron sheet required = 2πrh

= 2π×1×40 = 80π m²

A right curcular cylindrical tunnel of diameter 2 m and length 40 m is to be constructed from a sheet of iron. The area of the iron sheet required in m2, is
