Algebra.Com's Answer #794487 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! The area of the smaller \"pie wedge\" sector, A_sector = R^2*theta/2, \n" ); document.write( "where R = the radius, theta = the wedge angle. \n" ); document.write( "Since the chord is 3 cm from the center, the half angle is given by: \n" ); document.write( "arccos(3/R) = 1.1864. Thus the angle theta = 2.373. \n" ); document.write( "The area of the segment will be the sector area minus the triangular portion \n" ); document.write( "The area of this portion is 2(3*sqrt(R^2-3^2)/2) = 3*sqrt(55) \n" ); document.write( "The radius, R = sqrt(A/pi) = sqrt(201.062/pi) = 8 \n" ); document.write( "Finally, the area of the segment is 75.9296 - 3*sqrt(55) = 53.681 \n" ); document.write( " |
