MAFS.912.G-GMD.2.4 Practice
3D figures, cross sections, and rotations
2
Rotating a rectangle about an axis
the axis acts as a pivot line
for a vertical rotation, picture a revolving door: the rectangular door spins around a fixed axis/pole, creating a cylinder
the cylinder created is twice as wide as the rectangular door
the radius of the cylinder = width of the door, the height of the cylinder = height of the door
3
Multiple Choice
The two rectangles are rotated about their axes. What is the radius of the cylinder made by the figure on the RIGHT?
4
Rotating other 2d shapes about an axis
a triangle rotated about an axis on its side creates a cone
a rectangle rotated about an axis on its side creates a cone
a circle rotated about an axis on its diameter creates a sphere
