Dimensions of a Quarter. The circumference of a quarter is 7.85cm. What is the diameter? Radius? The area?
\n" ); document.write( "---------
\n" ); document.write( "Circumference = (pi)d
\n" ); document.write( "---
\n" ); document.write( "7.85 = (pi)d
\n" ); document.write( "---
\n" ); document.write( "Diameter = 7.85/3.14 = 2.5 cm.
\n" ); document.write( "-----
\n" ); document.write( "Radius + (1/2)(2.5) = 1.25 cm
\n" ); document.write( "-----
\n" ); document.write( "Area = (pi)r^2 3.14*1.25^2 = 4.91 sq cm
