Considering the varying points of view in congress and the likelihood of the house and senate to have opposing majority parties how can differences in proposed bills be worked out? Whose responsibilities is it

The radius  of the hemisphere is:
V=πh²(r-h/3)
because the volume of the hemisphere doesn't change , we measure the change in the volume in relation to the change in height:
dv/dt=π(h²-(1/3 dh/dt))+2h(r-h/3)dh/dt)
dv/dt=π(-h²/3+2hr-2h²/3)dh/dt
dv/dt=π(2hr-h²)dh/dtdv/dt=-2 ft³/h, height is 8 ft and radius of the hemisphere is 9 ft
-2=π(2h*9-h²)dh/dt
-2=π(2*8*9-8²)dh/dt
-2=π(80)dh/dt
dh/dt=-2/(π*80)
dh/dt=-0.008
