A circle is tangent to the x-axis and to the y-axis. The coordinates of its center are both positive. The area of the circle is 64pie. What are the coordinates of the point of tangency on the y-axis?
\n" ); document.write( ".
\n" ); document.write( "Area of a circle = (pi)r^2
\n" ); document.write( ".
\n" ); document.write( "They gave us the area as 64(pi)
\n" ); document.write( ".
\n" ); document.write( "64(pi) = (pi)r^2
\n" ); document.write( "64 = r^2
\n" ); document.write( "8 = r (radius)
\n" ); document.write( ".
\n" ); document.write( "Since the coordinates of the center are both positive, we know it is in the 1st quadrant.
\n" ); document.write( ".
\n" ); document.write( "point tangent on the y-axis is then (0,8)
\n" ); document.write( "
\n" );
