Algebra.Com's Answer #366679 by stanbon(75887) ![]() You can put this solution on YOUR website! The area of a 60 degree sector of a circle is 36pi cm^2. What is the diameter of the circle? \n" ); document.write( "That sector has 1/4 of the total area of the circle. \n" ); document.write( "--- \n" ); document.write( "Area of the circle = 4(36pi) = 144pi \n" ); document.write( "----- \n" ); document.write( "Area = (pi)r^2 \n" ); document.write( "---- \n" ); document.write( "Equation: \n" ); document.write( "(pi)r^2 = 144pi \n" ); document.write( "r^2 = 144 \n" ); document.write( "r = 12 \n" ); document.write( "------- \n" ); document.write( "Diameter = 2r = 24 cm \n" ); document.write( "================================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "================== \n" ); document.write( " |
