raw marks for a band 6? (1 Viewer)

[Kmara2nv]

If you're Band 5 or 6 material you could solve this:

The section of the curve y = rx/h (r and h are constants), between x = 0 and x = h rotated about the x-axis.
Show that finding the volume of the resulting solid revolution gives the formula for the volume of the cone.
