Algebra.Com's Answer #595726 by Boreal(15235) You can put this solution on YOUR website! The radius of the circle is the distance from the origin to (3,4). This is 3 units in x, 4 units in y, and the distance formula (Pythagorean Theorem) is 5. \n" ); document.write( "r=5; A =25* pi \n" ); document.write( "From the choices above, D is the only one close, and it fits with 25 pi or 78.5 square units. \n" ); document.write( " |
