Algebra.Com's Answer #36236 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The area of a 60 degree circle is 36 pi cm squared. What is the diameter of the circle? \n" ); document.write( "--------------- \n" ); document.write( "Area of a circle = pi(r^2) \n" ); document.write( "pi(r^2)=36 pi \n" ); document.write( "Divide both sides by pi to get: \n" ); document.write( "r^2=36 \n" ); document.write( "r=6 \n" ); document.write( "If r=6 the diameter = 2r = 12 cm \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
