SPHERE CYLINDER CONES Flashcards
is a three-dimensional round figure like a ball.
sphere
It has no edges nor vertices. It has only one surface, all of whose points are the same distance
from the center.
SPHERE
The distance from one point of the sphere to another, passing through its center
DIAMETER
FIXED DISTANCE FROM THE CENTER OF THE SPHERE TO ANY PART OF THE SPHERE
RADIUS
is a solid figure that has three faces (two circular bases and one
curved face on its body). It has two edges (the circles lining its bases), and it has no vertices.
CYLINDER
a solid that has a circular base, a curved face on its body, and a
single vertex.
CONE
WHAT IS A RIGHT CONE?
If the vertex is directly above the center of its circular base, it is
called a right cone.
WHAT IS AN OBLIQUE CONE?
If the vertex is NOT directly above the center of its circular base, it is
called a right cone.
HOW MANY FACES DOES A CYLINDER HAVE?
3
T / F CYLINDER HAS 1 CIRCULAR BASE
FACE
T/F SPHERE HAS 1 VERTEX
FALSE SPHERE DOES NOT HAVE EDGES OR VERTICES AND JUST HAVE 1 FACE
HOW MANY VERTEX, FACES, AND EDGES DOES A CONE HAVE?
1 VERTEX, 1 FACE, 1 EDGE
