we know that according to shell method volume of the solid generated by revolving the region bounded by y =f(x) and y = g(x) between x = a and x = b about line x = c is given by,
-----------------------------------------------------------------1)
where,
f(x) is the top curve above g(x) between x = a and x = b and we have a < b c
we have,
Hence we can say that,
Hence we can say that x ranges from x = 0 and x = 1 and as x ranges from x = 0 to x = 1 we have a = 0 and b = 1
we can see that y = x1/3 is the top curve above y = x2 between x =0 and x = 1 hence we have f(x) = x1/3 and g(x) = x2
solid is rotated about x = 2 hence we have c = 2
0 < 1 < 2 means a < b < c
Hence using formula 1) we can say that volume is given by,
