<text>This web computes the area of a circle. It contains two other cells besides this one:
AreaCirc -- which contains the formula for the area
of a circle, and where the result is placed.
r -- which is where the radius of the circle
may be entered.
Perform the calculation by positioning to the cell r, entering a value for the radius, and then positioning to the cell AreaCirc, and choosing Evaluate from the Special menu.
