Google translation (original was in Indonesian)
area bounded by the following curves rotated around the X axis rotating objects specified volume occurs.
y = x 2-4x +4, X axis and Y axis
My translation
Find the volume of revolution when the area bounded by y = x 2-4x +4, the x axis and the y axis is rotated about the x axis.
This is a concave up parabola, the vertex is at (2,0)
I think now it would be easier to do it in an attachment.
Ini adalah cekung up parabola, verteks di (2,0)
Saya pikir sekarang akan lebih mudah untuk melakukannya dalam lampiran.
I hope this helps Florin
