Algebra.Com's Answer #772090 by Kimani(1) You can put this solution on YOUR website! So, basically, when I placed these values on my TI-84 Plus graphing-calculator from Texas Instruments...\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "...and then pressed the [ENTER] key, the graph automatically draws 4 different circles that are roughly interlinking each other—but in different sizes—and as I watched each step carefully, I have recognized that the smallest circle is the one with the radius of 3.\r \n" ); document.write( "\n" ); document.write( "Although the center is located at coordinates (8, 9), the radius of the circle is measured 3 units for all 360 angles, no matter what the selected angle.\r \n" ); document.write( "\n" ); document.write( "So, therefore, (x + 8)² + (y - 9)² = 3 is the circle that has the smallest area, or radius. \n" ); document.write( " |
