Algebra.Com's Answer #115182 by SAT Math Tutor(36) ![]() You can put this solution on YOUR website! Begin by determining the angle covered in 20 minutes, which we know is 120 degrees or (2/3)*pi in radians. Since there are 360 degrees in a circle, this is 120/360 or 1/3 of the total circle.\r \n" ); document.write( "\n" ); document.write( "Then, find the area of the circle using the formula pi*r^2. In this case, r = 6 so the area is 36*pi.\r \n" ); document.write( "\n" ); document.write( "To, find the answer, multiply 1/3 by 36*pi to get 12*pi. \n" ); document.write( " |
