In this lesson our instructor talks about surface area and volume of sphere. First she discusses special segments and sphere. Then she talks about surface area and volume of a sphere. Four complete extra example videos round up this lesson.
Radius: endpoints are the
center and on the sphere
Chord: endpoints are points on
Diameter: endpoints on the
sphere and passes through center
Tangent: a line that
intersects the sphere at one point
A plane can intersect a sphere in a point, a circle, or a great circle
Hemisphere: half of a sphere separated by a great circle
Surface area of a sphere = 4πr2
Volume of a sphere = 4/3 (πr3)
