Mathematical Quiz 3

Start

See the picture a one-dimensional shape and must identify if the shape is rotated on its axis the resulting 3D shapes and then choose which of the options will give the correct volume calculation of the resulting shape. In the figure below the shaded part is rotated full rotation about the xψ axis. Identify the shape and choose the correct answer that will give the volume of the resulting 3D shape.

Vshape = Vconical cone + Vcylinder-Vicon

Question 1

Vshape = Vcylinder-Vicon

Vshape = Vfollowing cone+Vcylinder+Vcone
