The area of a sector of a circle is 44cm. What is the radius of the circle if the angle at the centre of the circle is 140?
\n" ); document.write( ".
\n" ); document.write( "sectorArea = n/360 * (pi)r^2
\n" ); document.write( "where
\n" ); document.write( "sectorArea is 44
\n" ); document.write( "n is number of degrees (140)
\n" ); document.write( "pi is 3.14
\n" ); document.write( "r is radius
\n" ); document.write( ".
\n" ); document.write( "44 = 140/360 * (3.14)r^2
\n" ); document.write( "44 = 7/18 * (3.14)r^2
\n" ); document.write( "44(18/7) = (3.14)r^2
\n" ); document.write( "44(18/7) = (3.14)r^2
\n" ); document.write( "113.1429 = (3.14)r^2
\n" ); document.write( "36.0328 = r^2
\n" ); document.write( "6 cm = r\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
