Surface area of a sphere opened up1970-01-01T00:00:00+00:00The surface area of a sphere is opened up to illustrate how the formula surface area = 4 π r2 can be understood. The animation starts with a lined sphere. The upper and lower hemisphere skins then open out to form the sphere’s enclosing cylinder.

Solids of revolution #5
Solids of revolution #5. This animation starts with a curve (y=fx) that goes above and below the X-axis. The positive and negative areas bounded by the curve are then limited by two boundaries to create two areas (red). This region then rotates about the X-axis to create a solid of revolution. Note that even though the curve becomes negative it still produces a solid figure.
