Marie's Volume Post

Things to remember:
  • The bases are circles
  • Radius is half a diameter
  • Diameter cuts a circle in half
  • Circumference is the perimeter of a circle
  • Pi is the ratio between circumference/diameter or 3.14



Formulas:
Circumference - pi (d) = c
Radius - d/2 = r
Diameter - 2r = d or c/pi

Area of a circle:
pi (r²) or pi (r) (r)

Net of a cylinder:













Formula:
lxw = a

pi (r) (r) = a
d = 2r
r = d/2

c = pi(d)



Here are the answers on our homework.
*I'm only showing one of each (diameter, circumference, radius) because Mr. Harbeck told me to.*






Here is a link on cylinders.
