Polyhedron
3 dimentional solid whose faces name a polyhedron by its/are polygons
Prism
A polyhedron with 2 bases
Pyramid
a polyhedron with 1 base
Isometric and Orthographic Drawings
A mathematicle way to show perspective
perspective
a way you see an object
Isometric
dot paper to make a figure
Orthographic
shows angle and lengths of all sides of a figure(front, top, and side)
Polyhedron Net
take a 3-d figure and unfold to see all shapes and dimentions
surface area
it is the sum of all areas of the polyhedrons faces
Prism
A polyhedron with 2 bases
*A 3-d figure with faces as polygon that has 2 bases
Volume
Amount of space it takes up
*how many cubic units(cm3) can fit inside
Formula for volume of prisms
V=B(base area)h(height)
Three ways to describe a circle
1. Diameter-distance across the circle through the center 2(r)=d
2. Radius-the distance from the center to any point on the circle d/2=r
3.Circumference-perimeter or distance around the circle
Circumference formula
C=Pi(d)
or C=2(Pi)(r)
circumference to diameter
d=C/Pi
formula for area of a circle
A=Pi r squared (A=Pi (r) (r) )
formula for surface area of a cylinder
SA=Pi(r squared) or Pi(d) times (2 Pi r)(h)
Formula for volume of Cylinders
V=Bh or V=Pi r squared (hieght)
