Algebra.Com's Answer #104142 by checkley77(12844)![]() ![]() ![]() You can put this solution on YOUR website! First you need to find the area of the 5m circle. \n" ); document.write( "a=pir^2 \n" ); document.write( "a=3.14*5^2 \n" ); document.write( "a=3.14*25 \n" ); document.write( "a=78.5 m^2 is the area. \n" ); document.write( "Now determine what percentage of the entire circle is contained in 75 degrees. \n" ); document.write( "75/360=.20833 or 20.833 % of the circle. \n" ); document.write( ".20833*78.5=16.35 m^2 is the area within the 75degree slice. \n" ); document.write( " \n" ); document.write( " |
