So we've just learned about how to measure Volume of the late, and in Fridays class we learned how to measure the Surface Area.
S.A (surface area) =4(pi)r-squared
This means in order to find the surface area of any object you multiply 4 by pi (3.14 repeated). Then you multiply total of 4xpi by the surface's area's radius (which is the circumference divided by 2). BUT YOU RADIUS IS ALWAYS SQUARED! If you do not square you radius your answer will be totally off.
that's pretty much it :) .... remember to check out the link that follows to study for exams!
NEXT SCRIBE THE JONATHAN! if your even there .... :P
