1. The area of a circle is 28 sq meters. What is the circumference?
\n" ); document.write( "Find r from the area:
\n" ); document.write( "\"pi%2Ar%5E2\" = 28
\n" ); document.write( "r = \"sqrt%2828%2Fpi%29\"
\n" ); document.write( ";
\n" ); document.write( "Find the circumference
\n" ); document.write( "C = \"2%2Api%2Ar\"
\n" ); document.write( "Replace r with\"sqrt%2828%2Fpi%29\"
\n" ); document.write( "C = \"2%2Api%2Asqrt%2828%2Fpi%29\"
\n" ); document.write( "enter into a calc
\n" ); document.write( "C = 18.758 m
\n" ); document.write( ":

\n" ); document.write( "2. A cylinder drum has a diameter of 3 yards and a volume of 65 cubic yards.
\n" ); document.write( " What is height of drum
\n" ); document.write( "Vol of a cylinder
\n" ); document.write( "\"pi%2Ar%5E2%2Ah\" = V
\n" ); document.write( "Find the radius: r = 3/2 = 1.5 yds
\n" ); document.write( "\"pi%2A1.5%5E2%2Ah\" = 65
\n" ); document.write( "\"pi%2A2.25%2Ah\" = 65
\n" ); document.write( "h = \"65%2F%282.25%2Api%29\"
\n" ); document.write( "using a calc
\n" ); document.write( "h = 9.1956 yds is the height
\n" ); document.write( ":
\n" ); document.write( ";
\n" ); document.write( "Check by finding the vol with this height
\n" ); document.write( "V = \"pi%2A1.5%5E2%2A9.1956\"
\n" ); document.write( "V = 65.00
\n" ); document.write( "
\n" );
