please help with all 3

1. Sketch the region between the functions. Then nd the volume given by revolving the region "around the x-axis". The region between {0:} = 2J7: and g(x) = x. 2. Find the volume given by revolving the region undery = x2 from x = 0 to x = 1 around 1: = 1. 3. Find the volume by revolving the region between f(x) = 1/36 (x - 3)2 and g(x) = '/36 -(x 3)2 around x = 3. from x=4~ to x=6. Don't calculate the integral. lust setup the integral
