Question 250352
<font face="Garamond" size="+2">



The area of a circle is given by *[tex \LARGE A\ =\ \pi r^2]


Divide the diameter by 2 to get the radius, square the result, then multiply by *[tex \LARGE \pi].  Leave the answer in terms of some number times *[tex \LARGE \pi] if you want the exact answer.  Or use an approximation of *[tex \LARGE \pi] to develop a numerical approximation of the area of the circle.
