SA= (πr²) + (2πrh) + (πr²)
The lenght of the rectangle is equal to the circumference of the circle.
Circumference (c) = πd (πxd) or 2πr (2xπxr)
radius (r) = distance (length) from the center to the outer ring.
radius (r) = distance (length) from the center to the outer ring.
pi (π) = is a constant and is aproximately equal to 3.14
diameter (d) = twice the length of the radius. (2r)
For example:
Volume of a Cylinder
Volume of a cylinder = area of base x height or πr² x h
For example:

You had very good diagrams, but i think you made a mistake at the volume of cylinder. You said pi,r,squared x b?
yeah. i typed it wrong. but i corrected it already. thanks for telling =)
nice job alex!
thanks nadine =)
