"C4 question, please help.?

the curve C has parametric equations x = sint , y = sin2t, 0<t<pi/2

a) find the area of the region bounded by C and the x-axis

and, if this region is revolved through 2pi radians about the x-axis,

b) find the volume of the solid formed

How do you do this question. Can anyone please show me step by step???"
