Unit 5, Lesson 6
What does Theorem 11-10 (Surface Area of a Sphere) state?
The surface area of a sphere is four times the product of pi and the square of the radius of the sphere (S.A. = 4 times pi times r^2).
What does Theorem 11-11 (Volume of a Sphere) state?
The volume of a sphere is four thirds the product of pi and the cube of the radius of the sphere (V = 4/3 times pi times r^3).
hemisphere
half of a sphere; a great circle divides a sphere into two hemispheres
diameter of a sphere
a segment passing through the center with endpoints on the sphere
radius of a sphere
a segment that has one endpoint at the center and the other endpoint on the sphere
great circle
the circle resulting from the intersection of a plane and a sphere in more than one point in which the center of the circle is also the center of a sphere
circumference of a sphere
the circumference of a great circle
center of a sphere
the given point in the middle of a sphere
sphere
the set of all points in space equidistant from a given point
