1. Area of a circle GIVENS: radius RESULTS: INTERMEDIATES:
HEADER:
ASSUMPTIONS
BODY:
radius
area (area of circle)
Area  CircleArea(radius)
radius is a positive number
Write down GIVENS, RESULTS, etc. again to emphasize that these are always part of the answer to a question like this.
GIVENS: X, Y, Z, scores out of 25
INTERMEDIATES
AvgOutOf25, average of X, Y, Z out of 25
T: not needed in the algorithm but we MUST give
a place for this result to be returned
RESULT: AvgPct, average of X, Y, Z out of 100
HEADER: AvgPct <-- MarkResult(X, Y, Z)
BODY:
(T, AvgOutOf25) <-- SumAndAverage( X, Y, Z )
AvgPct <-- AvgOutOf25 * 4
*** the big thing to discuss in this example is the naming of the variables
Area  3.14 * radius * radius
