1. Find the volume formed by rotating the region enclosed by x=5y and x=y^3 with y¡Ý0 about the yaxis.
2. Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis y=18x6x^2 , y=0 : about the yaxis.
PLease can anyone help me find the volume plz show ur works if u can so i can understand it better.
are you more comfortable finding volume by rotating about the xaxis.
Here is a good trick that works well in the first case.
Interchange the x and y variables in your equations and rotate about the xaxis, you get the same shape. (Basically I took the inverse)
BTW, I don't know what "..with y¡Ý0.." means.
